Question

If a pulley system with an ideal mechanical advantage of 2,000,000 is used in lifting a 2,000 lb car how far would the car move if the effort moved 2 ft

Answer 1

Answer;

1/million ft.

Explanation;

Mechanical advantage is a type of measure which calculates the amplified force gained by the mechanical system. It provides the ratio between the force applied to the load and the force needed to overcome the given force.

Mechanical advantage = Output force/input force or input arm distance/ output arm distance

therefore;  2 / 2,000,000 ft , or 1/million ft.

This is impractical .

Answer 2

1x10^-6 is the answer

2/2,000,000

=0.000001

or, 1x10^-6
