Question

Using a simple machine, a student is able to lift a 500N weight by applying only 100N. What is the mechanical advantage of the simple machine?

Answer 1

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

Answer 2

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
