The principle of moments states that for an object to be in equilibrium, the sum of the clockwise moments about a point must be equal to the sum of the anticlockwise moments about the same point.

The class of lever shown in fig.1 is a first-class lever. In a first-class lever, the fulcrum is located between the effort (force applied) and the load (resistance).

An example of a first-class lever in fig.1 is a seesaw or a crowbar.

To find the distance CA, we can use the principle of moments:

Clockwise moment = Anticlockwise moment

FA x AB = CA x FB

100 x 90 = CA x 50

9000 = 50CA

CA = 9000 / 50

CA = 180 cm

Therefore, the distance CA is 180 cm.

In a lever, the moment of the force on one side of the fulcrum is equal to the moment of the force on the other side of the fulcrum.

The lever in fig.1 is a

Examples of first-class levers include a seesaw, balance scale, and crowbar.

```

FA x AB = CA x CA

100 cm x 90 cm = CA x CA

CA = √(100 cm x 90 cm)
