By using levers and pulleys, the amount of force needed to move an object can be greatly reduced.

Answer;

5

Explanation;

  • Mechanical advantage is the ratio of output force divided by input force.
  • Mechanical advantage calculates the amplified force achieved by a mechanical system. It is given by dividing the force applied on a load by the force required to overcome the given force.

M.A = Output force/input force

Output force = 500 N, input force = 100 N

= 500 N/100 N

= 5
