Question

If the resistance force is 40 Newtons and the effort force is 20 Newtons, what is the mechanical advantage?

Answer 1

Mechanical Advantage = Load / Effort

= 40N/20N = 2

Answer 2

2 is the mechanical advantage of the machine.

Step-by-step explanation:

Mechanical advantage of a machine is defined as ratio of force exerted by the machine to the force exerted on the machine.

`\phi =\frac{\text{Resistance force}}{\text{Effort Force}}=(F_r)/(F_e)`

Resistance force,
`F_r` = 40 N

Effort force,
`F_e` = 20 N

`\phi =(40 N)/(20 N)=2`

2 is the mechanical advantage of the machine.
