Explanation:
MA of a machine is its mechanical advantage.
Mechanical advantage is the ability of a machine to multiply force so as to get a work done.
- This is done by minimizing effort and maximizing the load or output.
- A MA of a simple machine with a value of 3 suggests that such a machine will multiply input force by a factor of 3.
- Therefore, such a machine will amplify the force input into the system.
