The mechanical advantage of the lever is 3 and the right option is A.) 3.

What is mechanical advantage?

Mechanical advantage can be defined as the ratio of load to effort in a machine.

To calculate the mechanical advantage of the lever, we use the formula below.

Formula

  • M.A = y/x................ Equation 1

Where:

  • M.A = mechanical advantage of the lever
  • y = distance moved by effort (input arm)
  • x = distance moved by load (output arm)

From the question,

Given:

  • y = 3 m
  • x = 1 m

Substitute these values into equation 1

  • M.A = 3/1
  • M.A = 3.

Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.
