Question

Why the handle of an ordinary water handpump made longer?

• A. The mechanical advantage increases with the increase in effort arm.
• B. The mechanical advantage decreases with the increase in effort arm.
• C. No change in mechanical advantage.
• D. It will increase the efficiency.

Answer 1

The correct option is A

The mechanical advantage increases with the increase in effort arm.

As the mechanical advantage increases with the increase in effort erm, so a lesser effort is required to operate a handpump with a long handle. Because of this reason, the handle of an ordinary handpump is made longer.
