Question

Which of the following describes the mechanical advantage of a compound machine?

A: A compound machine's mechanical advantage is determined by the mechanical advantage of the simple machines that make it up.

B: The mechanical advantage of a compound machine is determined by the amount of effort force it requires.

C: The mechanical advantage of a compound machine is determined by the mass of the object.

D:The mechanical advantage of a compound machine is determined by the distance the force must travel.

Answer 1

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force.

Answer 2

Can you guess wat it iss?

Answer 3

my best guess is B, since it mentions force the machine requires
