Correct Answer - Option 2 : 0.83

CONCEPT:

  • Mechanical advantage: It is a form of calculation that measures the amplified force taken by the mechanical system.
    • It gives the ratio between the force applied to the load and the force needed to overcome the given force.
    • It is a unitless expression since the two ratio quantities are the force.
    • Mechanical advantage is also defined as the force created by the machine to the for applied on it.

The formula of mechanical advantage is given as:

MA = Load/Force = L/F

EXPLANATION:​

Given, that F = 60 N, L =  kg

Also, Force is given by,

Force = Load + Friction

F = L + f

f = F - L = 60 - 50 = 10

And,

MA = 50/60 = 0.83

So, the correct option is 0.83.
