Answer 2

Calculation of the Right Lever Arm

To determine the length of the right lever arm, we can use the principle of moments. According to this principle, the sum of the clockwise moments about a point is equal to the sum of the counterclockwise moments about the same point when an object is in equilibrium.

In this case, the left lever arm is given as 10 cm, and the force applied to the left end of the lever is 72 N. The force applied to the right end of the lever is 12 N. Let's assume the right lever arm length is "x" cm.

Using the principle of moments, we can set up the equation:

Clockwise moment = Counterclockwise moment

The clockwise moment is given by the product of the force (12 N) and the length of the right lever arm (x cm).

The counterclockwise moment is given by the product of the force (72 N) and the length of the left lever arm (10 cm).

Therefore, we have:

12 N * x cm = 72 N * 10 cm

To find the value of "x," we can solve this equation:

12x = 720

Dividing both sides by 12, we get:

x = 60 cm

Therefore, the length of the right lever arm is 60 cm.
