An endless belt of 8m pitch length is to drive a 750 mm diameter pulley the belt is 10 mm thick and the motor pulley is 300 mm in diameter calculate the correct centre distance if an amount of 15 mm is to be added to obtain some initial belt tension what is the speed ratio

Answers

Answer 1

To calculate the correct center distance and speed ratio, we can use the formula for the pitch diameter of a pulley.the correct center distance is 1105 mm, and the speed ratio is approximately 2.40625.

First, let's calculate the pitch diameter of the 750 mm diameter pulley:Pitch Diameter = Diameter + (2 x Belt Thickness) = 750 mm + (2 x 10 mm) = 770 mmNext, let's calculate the pitch diameter of the motor pulley:Pitch Diameter = Diameter + (2 x Belt Thickness) = 300 mm + (2 x 10 mm) = 320 mmThe center distance is the sum of the pitch diameters of the two pulleys, plus the added tension amount:Center Distance = Pitch Diameter of Pulley 1 + Pitch Diameter of Pulley 2 + Added TensionCenter Distance = 770 mm + 320 mm + 15 mm = 1105 mmTo calculate the speed ratio, we can divide the pitch diameter of the driver pulley by the pitch diameter of the driven pulley:Speed Ratio = Pitch Diameter of Driver Pulley / Pitch Diameter of Driven PulleySpeed Ratio = 770 mm / 320 mm = 2.40625

Which level of acceleration should you use when accelerating on a short highway entry ramp?

Answers

The higher level of acceleration should be used when accelerating on a short highway entry ramp.

Given data:

When accelerating on a short highway entry ramp, you should use a higher level of acceleration to safely merge with the traffic already on the highway. This is particularly important when the entry ramp is short, as you need to reach the speed of the highway traffic and find a suitable gap to merge into the flow.

Using a higher level of acceleration allows you to match the speed of the vehicles on the highway more quickly and efficiently, reducing the risk of causing disruptions or potential hazards. It's essential to accelerate smoothly and decisively to ensure a safe merge onto the highway. Always follow traffic rules and guidelines while merging onto highways to ensure the safety of yourself and others.

How a car break works?

The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.

Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.

The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

The displacement of a particle which moves along the s-axis is given by; = (−2 + 3)−0.5 Where s is in meters and t is in seconds. Determine the time at which the acceleration is zero.

Answers

The time at which the acceleration is zero is given as 4.66 seconds

How to solve for the time

First we have to solve for the velocity. To do this, we would have to take the derivative.

[tex]s = e^-0.5t (3 t - 2)[/tex]

Then velocity =

[tex]ds/dt = e^-0.5t (4 - 1.5 t)[/tex]

The acceleration can be gotten by finding the second derivative

[tex]a = dv/dt = e^-0.5t (.75 t - 3.5)[/tex]

To find t at acceleration = 0

We have

[tex]0 = e^-0.5t (.75t - 3.5)[/tex]

This gives t to be

Answers

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.

What is travel speed?

The travel speed of the welding flame or gun across the workpiece is simply measured in millimeters per minute.

Travel speed, along with voltage and amperage, is one of three factors in arc welding that affect the amount of heat input.

What is the calculation that justifies the above answer is?

We are given the following:


Melting temperature = 1650 K

k = (3.33 * 10⁻⁶) * (1,650)²

k = 9.066 J/mm^3

The formula for velocity here is given as:

V = f1 * f2 * Rh / (k*A)

V = 0.9 * 0.6 * 3000 / (9.066*25)

V = 7.147 mm/s

A wheel spins at a constant angular speed of 24rad/s.How many revolutions will the dosk go through in 5minutes?​

Answers

Answer:

The wheel will go through 1146 revolutions in 5 minutes.

Explanation:

We can the formula:

[tex]\boxed{\omega = \frac{2 \pi}{T}}[/tex]

where

ω ⇒ angular speed (24 rad/s),

T ⇒ time period (? s),

and solve for T to find the time it takes for the wheel to complete one revolution.

⇒  [tex]24 = \frac{2 \pi}{T}[/tex]

⇒  [tex]T = \bf \frac{2 \pi}{24}[/tex]  s

This means it takes [tex]\bf \frac{2 \pi}{24}[/tex] seconds for the wheel to complete one revolution.

Now, using the unitary method,

In [tex]\frac{2 \pi}{24}[/tex] seconds          ⇒    1 revolution completed

In 1 second              ⇒    1 ÷ [tex]\frac{2 \pi}{24}[/tex]   =  [tex]\frac{24}{2 \pi}[/tex]  revolutions completed

In (5 × 60 = ) 300s  ⇒     [tex]\frac{24}{2 \pi}[/tex]   ×  300   = 1145.9

Answers

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m

How to draw Shear Force and Bending Moment Diagram?

A) We can see the beam loaded in the first image attached.

For the shear diagram, let us calculate the shear from point load to point load.

From A to C, summing vertical to zero gives; ∑fy = 0: -20 - V = 0

V = -20 KN

From C to D, summing vertical to zero gives; ∑fy = 0: -20 + 48 - V = 0

V = 28 KN

From D to E, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - V = 0

V = 8 KN

From E to B, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - 20 - V = 0

V = -12 KN

For the bending moment diagram, let us calculate the bending moment from point load to point load.

At point A, the bending moment would be zero. Thus, M_A = 0 KN.m

At point C, taking moment about point C and equating to zero gives;

M_C = 0. Thus; 20(0.225) + M = 0

M = -4.5 KN.m

At point D, taking moment about point D and equating to zero gives;

M_D = 0. Thus; 20(0.525) - 48(0.3) + M = 0

M = 3.9 KN.m

At point E, taking moment about point E and equating to zero gives;

M_D = 0. Thus; 20(0.75) - 48(0.525) + 20(0.225) + M = 0

M = 5.7 KN.m

At point B, taking moment about point E and equating to zero gives;

M_E = 0. Thus; 20(1.05) - 48(0.825) + 20(0.525) + (20 * 0.3) + M = 0

M = 2.1 KN.m

2) From the attached diagrams, we can deduce that;

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m
