Question

Choose the correct expression for mechanical advantage.

• A. M.A = $\frac{\text{Load}}{\text{Effort}}$​
• B. M.A = $\frac{\text{Effort}}{\text{Load}}$​​
• C. M.A = $\frac{\text{Vertical height}}{\text{Inclined Length}}$​​
• D. M.A = $\frac{\text{Inclined Length}}{\text{Vertical height}}$​​

Answer 1

The correct option is A

M.A = $\frac{\text{Load}}{\text{Effort}}$​

The mechanical advantage of a machine is a factor by which a machine multiplies the force applied. It is defined as the ratio between the load to the effort. Mechanical advantage can take values greater than 1, 1 or less than 1.

M.A = $\frac{Load}{Effort}$
