MACHINE

A machine is any devices that make work easier. Things to consider in a machine are;

  • Mechanical Advantage
  • Velocity ratio
  • Efficiency

Given that a machine that exerts a force of 160 N on an object when a person exerts a force of 20 N on the machine.

The mechanical advantage (M.A) of a machine is the ratio of load (L) to effort (E).

The given parameters are;

Load = 160N = force exerts by the machine

Effort = 20N = force exerts by the person

M.A = L/E

M.A = 160 / 20

M.A = 8

Therefore, the mechanical advantage of the machine is 8.
