David wishes to accumulate $1million by the of 20 years by making equal anual end of year deposits over the next 20 years if david can earn 10%on his envestment how much he deposit at the end of each year
Answer:
Explanation:
We can use the formula for calculating the future value of an annuity to determine the amount that David needs to deposit each year. The formula is:
A = F / ( (1 + r)^n - 1) / r
where:
A is the annual deposit
F is the future value ($1 million)
r is the interest rate (10%)
n is the number of years (20)
Plugging in the values, we get:
A = 1000000 / ( (1 + 0.1)^20 - 1) / 0.1
A = $38,851.68
Therefore, David needs to deposit $38,851.68 at the end of each year for 20 years to accumulate $1 million.
the pressure drop needed to force water through a horisontal 1in diameter pipe is 0.5 psi for every 11 ft length of pipe. determine the shear stress on the piupe wall determine the shear stress at distances 0.3 amnd 0.5 in away from the pipe wall
The shear stress at distances 0.3 and 0.5 in away from the pipe wall 0.06 psf For every 12-ft length of pipe, 0.60 psi of pressure drop is required to force water through a horizontal 1-in diameter pipe.
P = 4 L w / D to determine the shearing stress at the wall. So
w = P D / 4L
= (0.6 psi)(144 in2/ft2) (1 in)(1ft/12 in)] / 4(12 ft)
= 0.15 lb/ft2 (result)
As the pipe's centerline gets further away, the shear stress now varies linearly.
τ = 2 τw (r/D)
The centerline is 0.5 inches from the wall in this case, therefore r and are both equal to 0 psf (result).
r = 0.2 inches at 0.3 inches from the wall.

. consider a large windmill 15 m in diameter. on a windy day, suppose that the windmill entrains a stream of air at a speed of 45 km/hr. downstream of the windmill, the entrained stream exits over a large diameter at a speed of 24 km/hr. the pressure equals atmospheric pressure at both inlet and outlet. find the power (in megawatts) generated by the windmill. density of air is 1.2 kg/m3.
The power generated due to the windmill is P = approximately 7.9 megawatts
We must determine the difference in kinetic energy between the input and outlet air streams in order to calculate the power produced by the windmill.
We can begin by converting the following speeds from km/hr to m/s:
45 km/hr equals 12.5 m/s (45 * 1000/3600).
24 km/h is equal to 24 * 1000/3600, or 6.67 m/s.
The inlet area is determined by: A1 = * (15/2)2 = 176.71 because the windmill entrains air over a circle with a diameter of 15 m.
Similar calculations can be made for the outlet area, where A2 = * (15/2 + x)^2, where x is the separation between the windmill and the outlet.
The formula for calculating the mass flow rate of air is m = * A1 * u1 = 1.2 kg/m3 * 176.71 m2 * 12.5 m/s = 2650 kg/s.
The outflow velocity and the inlet can be connected using the continuity equation.
A1 * u1 = A2 * u2
u2 = (A1 * u1) / A2
Next, we can calculate the change in kinetic energy between the inlet and outlet air streams:
ΔKE = 0.5 * m * (u2^2 - u1^2)
P = ΔKE / t, where t is the time
load for 10^4 cycles, factor of 1.5, we can set t = 10^4 * 1.5.
P = 0.5 * m * (u2^2 - u1^2) / t
P = 0.5 * 2650 kg/s * (6.67 m/s^2 - 12.5 m/s^2) / (10^4 * 1.5)
P = approximately 7.9 megawatts

According to the question, the total deformation of the specimen is 0.0055 mm.
What is deformation?
Deformation is a process of changing the shape or size of an object due to an external force. It is an irreversible process that occurs when a material is subjected to an external force that exceeds its yield strength. Deformation can be divided into two main categories: elastic deformation and plastic deformation.
The total deformation of a 5-mm-thick sheet of vinyl subjected to a 1.5 kN tensile load can be determined using the equation: Δ = (FL³)/(3EI)
Where:
F = 1.5 kN
L = 50 mm
E = 3.1 GPa
[tex]I = bh^{3/12}[/tex]
Since the thickness (h) of the sheet is 5 mm, I = [tex]5^{3/12[/tex] = 0.208 mm⁴.
Therefore, the total deformation of the specimen can be calculated as:
Δ =[tex](1.5\times 50^3)/(3\times 3.1 \times10^9 \times 0.208\times10^{-12})= 0.0055 mm[/tex]

a long vertical pipe filled with water is equipped with pressure gauges at each end as shown below. an engineering student observing the pipe notices that each pressure gauge reads the same value. is water flowing in the pipe? if so, in what direction is the water flowing?
No water is flowing as both gauges read the same value, indicating equal pressure at both ends of the pipe. Water would be flowing if there was a difference in pressure, with flow direction towards the lower pressure end.
Water is not flowing in the pipe as both pressure gauges read the same value. This indicates that there is no difference in pressure between the two ends of the pipe, which is a necessary condition for water to flow. In a pipe filled with fluid, flow occurs from high-pressure regions to low-pressure regions. If the pressures at both ends are equal, then there is no driving force for fluid to flow, and hence the fluid remains at rest. It's important to note that pressure alone does not determine the flow of fluid in a pipe. Other factors such as viscosity, pipe diameter, and fluid velocity also play a role.

a horizontal curve on a single-lane freeway ramp is 400 ft long, and the design speed of the ramp is 45 mi/h. if the superelevation is 10% and the station of the pc is 18 25, what is the station of the pi and how much distance must be cleared from the center of the lane to provide adequate stopping sight distance?
The station of the PI (Point of Intersection) can be determined using the length of the horizontal curve and the design speed of the ramp. The formula for calculating the station of the PI is given by:
PI = PC + A / 2 * R
Where PC is the station of the PC (Point of Curvature), R is the radius of the curve, and A is the degree of curvature. The degree of curvature can be calculated as follows:
A = 360 * L / (2 * π * R)
Where L is the length of the curve and π is the mathematical constant pi.
Substituting the given values, we get:
R = V^2 / (127 * sin(2A))
Where V is the design speed in feet per second. Substituting the design speed of 45 mi/h (which is equal to 67.1 ft/s) and solving for R, we get a radius of 582.7 ft.
A = 360 * 400 / (2 * π * 582.7) = 69.07 degrees
Substituting the calculated values of R and A into the formula for PI, we get:
PI = 18 + 25 + 400 / 2 * 582.7 = 188 + 200 = 388 + 25 = 413
So the station of the PI is 413.
Adequate stopping sight distance is the distance a driver needs to be able to see ahead of the vehicle to stop if a hazard is encountered. The formula for calculating adequate stopping sight distance is given by:
SSD = T * V + (V^2) / (2 * a)
Where T is the reaction time of the driver, V is the design speed in feet per second, and a is the deceleration rate of the vehicle, which is assumed to be a constant of 10 ft/s^2. Substituting the given values and solving for SSD, we get:
SSD = 2 * 67.1 + (67.1^2) / (2 * 10) = 134.2 + 452.41 = 586.61 ft
So, adequate stopping sight distance is 586.61 ft.
To provide adequate stopping sight distance, the distance must be cleared from the center of the lane. The amount of clearance needed depends on the width of the lane and the superelevation rate. For a single-lane ramp with a superelevation rate of 10%, the distance from the center of the lane to the edge of the road should be approximately equal to half of the adequate stopping sight distance, which is 586.61 ft / 2 = 293.31 ft.
In conclusion, the station of the PI on the horizontal curve on the single-lane freeway ramp is 413, and to provide adequate stopping sight distance, a distance of 293.31 ft must be cleared from the center of the lane.

in which mechanical test is a specimen deformed, usually to fracture, with a gradually increasing load that is applied uniaxially along the long axis of the specimen, i.e. the specimen is pulled apart?
The mechanical test that involves deforming a specimen to fracture with a gradually increasing load applied uniaxially along the long axis of the specimen is called a tensile test.
A tensile test, also known as a tension test, is used to determine the mechanical properties of a material, such as its strength, ductility, and toughness. The test is performed by clamping a cylindrical or rectangular specimen between two grips, and then applying a load to the specimen in a direction that is parallel to its longitudinal axis. The load is gradually increased until the specimen fractures, and the stress-strain behavior of the material is recorded during the test.
During a tensile test, the stress in the material increases until the maximum stress that the material can withstand is reached. This maximum stress is known as the tensile strength. The amount of strain that occurs before the specimen fractures is a measure of the material's ductility. The toughness of the material is determined by the amount of energy required to fracture the specimen.
Tensile tests are used to determine the mechanical properties of a variety of materials, including metals, polymers, composites, and ceramics. The results of tensile tests can be used to select materials for engineering applications, optimize processing conditions, and evaluate the performance of materials under different loading conditions.
In conclusion, a tensile test is a mechanical test in which a specimen is deformed to fracture with a gradually increasing load applied uniaxially along the long axis of the specimen.

if the highest pipe in a hot water hydronic heating system is 12 feet above the inlet of the expansion tank, what a the desired pressure in the expansion tank?
The desired pressure in the expansion tank, if the highest pipe in a hot water hydronic heating system is 12 feet above the inlet of the expansion tank will be 6.58 pascal.
Why are expansion tanks necessary?When water heats up in the water heater, it expands thermally. The expansion tank is made to handle this process and control excessive water pressure. Excessively high water pressure can harm the water heater as well as supply pipe joints and valves on plumbing fittings. Closed-loop and, ideally, airless hydronic systems are available. The expansion of water requires heat. Every time the water is heated without an expansion tank, the pressure relief valve would open.
Hence the pressure of an expansion tank:
P = (H ÷ 2.31) + 5
H = 12 feet = 3.658 meter
P = ( 3.658 ÷ 2.31) + 5
P = 1.583 + 5

A wound-field dc motor is driving a load whose torque requirement increases linearly with speed and reaches 5 Nm at a speed of 1,400 rpm. The armature terminal voltage is held to its rated value. At the rated Bf , the no-load speed is 1,500 rpm, and the speed while driving the load is 1,400 rpm. If Bf is reduced to 0. 8 times its rated value, calculate the new steady state speed
New speed = 0.8 * Rated speed = 0.8 * 1500 rpm = 1200 rpm. The new steady state speed with 0.8 times the rated magnetic field strength would be 1200 RPM.
To calculate the new steady state speed, we need to first understand how the motor's speed is influenced by the magnetic field strength (Bf). When the magnetic field strength decreases, the motor's back-EMF will decrease, which will result in an increase in the armature current and hence an increase in the torque produced by the motor. Since the load torque requirement increases linearly with speed, the new steady state speed can be calculated as follows:
New torque produced by the motor = (0.8 * Rated Bf) * armature current
New speed = (Torque produced by the motor) / (Load torque requirement) * (Rated speed)
Since the armature terminal voltage is held constant, the armature current will increase proportional to the decrease in magnetic field strength. Hence, the new steady state speed can be calculated as follows:
New speed = (0.8 * Rated Bf) / (Rated Bf) * (Rated speed) = 0.8 * Rated speed = 0.8 * 1500 rpm = 1200 rpm.
Therefore, the new steady state speed with 0.8 times the rated magnetic field strength would be 1200 RPM.

A firm wants to sponsor a new engineering lab at a local university.
This requires $4.0M to construct the lab, $1.5M to equip it, and
$750,000 every 6 years for new equipment. What is the required
endowment if the university will earn 8% interest on the funds?
Answer:
Explanation:
Find the present value of the cost of new equipment every 6 years using the formula for present value of an annuity:
PV = A * (1 - (1 + r)^-n) / r
Where:
PV = Present value
A = Annuity payment
r = Interest rate
n = Number of periods
In this case, A = $750,000, r = 8%, and n = 6 years. Plugging these values into the formula, we get:
PV = $750,000 * (1 - (1 + 0.08)^-6) / 0.08 = $3,519,702.81
Add the present value of the cost of new equipment to the initial construction and equipment costs:
Total present value = $4,000,000 + $1,500,000 + $3,519,702.81 = $9,019,702.81
This is the amount of money that the university needs to have in an endowment in order to earn 8% interest and cover the costs of the lab and new equipment.
Therefore, the required endowment is $9,019,702.81.

The correct position of the vertical adjustment selector would be 5 volts.
What is Volts?
Volts refer to the unit of electric potential difference or electrical pressure. It is the derived SI unit of measure for electric potential and is represented by the symbol V. It is defined as the difference in electric potential between two points in a circuit that will cause one ampere of current to flow through a resistance of one ohm.
In other words, it is the difference in electric potential energy per unit charge between two points. In basic terms, it is the amount of energy that is needed to move a charge between two points of a circuit, or the amount of electric potential difference between two points in a circuit.
