Question

The mechanical advantage of a compound machine is equal to the one simple machine that has the greatest mechanical advantage.

Answer 1

That's false.  The mechanical advantage of a compound machine
is the product of the mechanical advantages of all the individual
component simple machines that make it up.

Answer 2

Answer:

True

Explanation:

A compound machine is basically a combination of two or more simple machines. Each simple machine has certain mechanical advantage but it might not be enough to perform a role where in a compound machine is required. Thus, the combination of mechanical advantage of individual simple machines would be equal to the mechanical advantage of the compound machine. The compound machine can be equated to a simple machine having greatest mechanical advantage.
