if the average normal stress in each of the 20-mm-diameter bars is not allowed to exceed 150 mpa, determine (a) the maximum force p that can be applie
The maximum force that can be applied to a 20-mm-diameter bar without exceeding the average normal stress of 150 MPa is approximately 0.063 N.
The maximum force that can be applied (P) to a 20-mm-diameter bar can be determined using the formula for normal stress:
σ = P/A,
where σ is the normal stress, P is the force, and A is the cross-sectional area. To find the maximum value of P, we need to find the cross-sectional area of the bar.
A = πr^2,
where r is the radius of the bar. Plugging in the values,
[tex]A = π * (0.02 m)^2 = 3.14 * 0.0004 m^2.[/tex]
Since the maximum normal stress is given as 150 MPa, we can use the equation to find the maximum force:
[tex]P = σ * A = 150 MPa * 3.14 * 0.0004 m^2 = 0.063 N[/tex].
So the maximum force that can be applied to a 20-mm-diameter bar in this case is approximately 0.063 N.

the stock room technician gave you 6.0 g of naf. how many milliliters of a 300 mm solution can you make?
To determine the amount of milliliters of a 300 mM solution that can be made from 6.0 g of Naf, we first need to calculate the number of moles of Naf.
How to calculate the amount of solution can you make?
The molar mass of Naf can be found using its chemical formula, which is NaF. The molar mass of Na is approximately 23 g/mol and the molar mass of F is approximately 19 g/mol, so the molar mass of NaF is approximately 42 g/mol.
Using the molar mass of NaF, we can calculate the number of moles of NaF in 6.0 g:
6.0 g ÷ 42 g/mol = 0.143 mol
Next, we can use the molarity of the solution (300 mM) to find the number of milliliters of the solution that can be made from 0.143 moles of NaF:
0.143 mol ÷ 300 mM = 0.000476 L = 476 mL

The mover wants to move 3000-N piano to a height of 2m. If
he uses a ramp, he needs to pushed the piano 10-m using a
force of 800N. What is the efficiency of the ramp?
Efficiency of a system is defined as the ratio of the useful output power to the input power. In this case, the useful output power is the work done in lifting the piano to a height of 2 meters.
The input power is the work done in pushing the piano up the ramp over a distance of 10 meters.
The work done in lifting the piano to a height of 2 meters can be calculated as follows:
W = F x d
W = 3000 N x 2 m = 6000 J
The work done in pushing the piano up the ramp over a distance of 10 meters can be calculated as follows:
W = F x d
W = 800 N x 10 m = 8000 J
The efficiency of the ramp can be calculated as the ratio of the useful output power to the input power:
Efficiency = (Useful output power) / (Input power)
Efficiency = 6000 J / 8000 J
Efficiency = 0.75 or 75%
In conclusion, the efficiency of the ramp in this scenario is 75%. This means that for every 100 units of energy put into pushing the piano up the ramp, 75 units of energy are used to lift the piano to the desired height, and 25 units of energy are lost as heat, noise, friction, or other forms of waste energy. To improve the efficiency of the ramp, one could try reducing the friction or waste energy generated during the process.

According to the calculations above, the square cross section's needed width is roughly 28.83 mm.
In conclusion, we must calculate the maximum bending stress in order to establish the needed dimension of the square cross section for the cantilevered rod. As a result, the maximum bending moment can be determined as follows:
where b is the square's cross-sectional breadth.
The formula for calculating the distance, y, between the neutral axis and the outside surface is
y = b / 2
The material's maximum stress that it can withstand for an unlimited number of cycles without failing, or the endurance limit, is known as AISI 1050 hot-rolled steel. The mechanical properties of hot-rolled AISI 1050 steel allow one to determine its endurance limit.
By finding b's value, we can determine that the square cross section's necessary width is roughly 28.83 mm.
σ_max = (M * y) / I
Where L is the 1.2 m long rod's length and P is the 1 kN load.
M = P * L
M = 1 kN * 1.2 m = 1.2 kN * m
I = (b^4) / 12

A 19,400-N weight is raised using a jackscrew having a pitch of 5.00 mm and a handle length of 255 mm. What force must be applied?
To calculate the force required to raise the 19,400 N weight, we can use the equation for mechanical advantage of a screw jack.
How to calculate the force required to raise the 19,400 N weight?
MA = Pitch / Handle Length
Where MA is the mechanical advantage, Pitch is the distance the screw advances with one complete turn and Handle Length is the distance between the center of the screw and the point where the force is applied.
In this case, we have:
MA = 5.00 mm / 255 mm = 0.0196
So, the force required to raise the weight is:
F = Weight / MA = 19,400 N / 0.0196 = 997,447 N

calculate the net work done on the satellite as it moves once around the orbital path. submit the final answer here and show your work in your dropbox submission.
To calculate the net work done on the satellite as it moves around the orbital path, you need to calculate the gravitational potential energy of the satellite at different points in the orbit. The change in gravitational potential energy is equal to the net work done on the satellite.
To calculate the gravitational potential energy, use the following formula:
GPE = mghwhere m is the mass of the satellite, g is the gravitational acceleration, and h is the height of the satellite above the centre of the Earth.
Once you have calculated the gravitational potential energy of the satellite at different points in the orbit, subtract the initial GPE from the final GPE to calculate the net work done on the satellite. Show your work in your Dropbox submission.

the maximum noise voltage that may appear at the input of a logic gate without changing the logical state of its output is termed as
The maximum noise voltage that can enter a logic gate's input without affecting the output's logical state is known as the noise margin.
What is Voltage?Voltage is an electrical potential difference between two points. It is measured in volts and is the force that causes electrons to move through an electrical circuit or between two points in a circuit. Voltage is created by a power source, such as a battery or generator, and is the pressure that pushes electrons through a circuit.
Voltage is also sometimes referred to as electromotive force (EMF) or electric potential. Voltage can also be generated by a dynamic force such as a changing magnetic field or a mechanical force like a falling weight.
