A seesaw is unbalanced with two people of different masses sitting equal distances from the center. Which of the following will result in equilibrium?

The larger person moving further away from the center.

Moving the smaller person closer to the center.

Moving the smaller person further from the center.

Making the larger person do nothing.

The easiest way to open a heavy door is by applying the force

Near the hinges

In the middle of the door

At the edge of the door far from the hinges

At the top of the door

3. Which type of lever is this?

First Class Lever

Second Class Lever

Third Class Lever

A see saw is an example of a:

1st class lever

2nd class lever

3rd class lever

What is the unit of moment f force?

N/m

Moment is a quantity that tells turning effect of a force about turning point.

TRUE

FALSE

What is the correct equation for calculating a perpendicular distance?

perpendicular distance = force x moment

perpendicular distance = force / moment

perpendicular distance = moment / force

10.

The moment of force defined as the product of....

the force and the acceleration

the force and the perpendicular distance

the force and the velocity

the force and the perpendicular distance from pivot

11.

State the principle of moments.

When a system is in equilibrium, the sum of the total clockwise moment is equal to the sum of the total anti-clockwise moment about the same pivot.

When a system is in equilibrium, the sum of the total clockwise moment is greater the sum of the total anti-clockwise moment about the same pivot.

When a system is in equilibrium, the sum of the total clockwise moment is less than the sum of the total anti-clockwise moment about the same pivot.

When a system is in equilibrium, the sum of the total clockwise moment is equal to the sum of the total anti-clockwise moment about the different pivot.

12.

What is the formula for moments?

Force = Distance x time

Moment = Force $\div$ distance

Moment = Force x distance

Force = distance x Moment

13.

When an object is in equilibrium, which equation is true?

Clockwise moment = anticlockwise moment

Clockwise moment + anticlockwise moment = 0

Clockwise moment / anticlockwise moment = 0

Clockwise moment + anticlockwise moment = resultant force

14.

What is the moment produced by the 15 N?

15 Nm (clockwise)

150 Nm (anti - clockwise)

1.5 Nm (anti - clockwise)

0.15 Nm (clockwise)

15.

We use levers to make work easier.?

True

False

16.

Which statement is correct?

All the forces are equal in size.

The resultant force on the beam is in the opposite direction to the resultant turning effect.

The resultant force on the beam is zero and the resultant turning effect on the beam is zero.

The total upward force is twice the total downward force.

17.

The point through which the whole weight of the body acts is called

Inertial Point

Center of gravity

Centriod

Central point

18.

Where will be the centre of gravity of a uniform rod lies ?

At its end

At its middle point

At its centre of its cross sectional area

Depends upon its material

19.

What is one way you might increase the stability of an object?

Lower the center of gravity

Raise the center of gravity

Increase the height of the object

Shorten the base of the object

20.

Which one describe the point through which the whole weight of the body acts?
