Two forces each of magnitude 25N acts in opposite direction at the opposite end of a circular ring. If the diameter at the ring is 65cm. Calculate the magnitude of the couple acting on the ring​.

Two Forces Each Of Magnitude 25N Acts In Opposite Direction At The Opposite End Of A Circular Ring. If

Answers

Answer 1

Answer:

The magnitude of the couple is 16.25 Nm.

Explanation:

A couple is a force that always produce a turning effect of objects on which it is applied. It has applications in doors, taps, revolving doors etc. Couple is a two equal but opposite force applied on an object.

couple = force x length

From the given question, the couple acting on the ring can be determined as;

couple = 25 x 0.65

           = 16.25 Nm

The magnitude of the couple is 16.25 Nm.

A ball is released from a height of 20 metres. Calculate; 1. The time it takes to fall 2. The velocity with which it hits the ground

Answers

Answer:

Final velocity of ball = 20 m/s

Explanation:

Given:

Height when ball released = 20meter

Find;

Time taken to fall

Final velocity of ball

Computation:

Initial velocity of ball = 0 m/s

Acceleration due to gravity = 10 m/s²

Using equation of motion;

S = ut + (1/2)(g)(t²)

20 = (0)(t) + (1/2)(10)(t²)

20 = 5(t²)

(t²) = 20 / 5

(t²) = 4

Time taken to fall = 2 second

V = u + at

V = 0 + (10)(2)

Final velocity of ball = 20 m/s

9. How is spring potential energy determined from a force versus position graph?

Answers

Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.

Explanation:

:)

By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

What will be the potential energy?

As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.

For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by  [tex]PE=mgh[/tex]

Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.

So this extension will be found out by the force and displacement  graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the

[tex]PE= F\times X[/tex]

[tex]F=mg[/tex]  weight of the mass

X= deflection of the spring

Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

the shock absorbers in a car act as a big spring with k= 21900 N/m. when a 92.5 kg person gets in, how far does the spring stretch?

Answers

Answer: 0.04139m

Explanation:

First, we need to calculate the weight of the man which will be:

Weight = mass × acceleration due to gravity

Weight = mg

Weight = 92.5 × 9.8

Weight = 906.5N

Then, we calculate the force which will be:

F = kx

mg = kx

x = mg/k

x = 906.5/21900

x = 0.04139m.

The spring stretched for 0.04139m.
