Question

A machine displaces a load of 125kgf through a distance of 0.30m, while an effort of 12.5kgf acts through a distance of 4.0m. calculate the mechanical advantage.

Answer 1

1. Definition:

The ratio of force produced by the machine to the force applied to it.

Mechanical advantage = $\frac{load}{effort}$

2. Solution:

Given that,

Load = 125 kgf

Load arm = 0.30m

Effort = 12.5kgf

effort arm = 4.0m

Mechanical advantage = $\frac{load}{effort}$

Mechanical advantage = $\frac{125}{12.5}$

mechanical advantage = 10

3. Conclusion:

Hence, the mechanical advantage is 10.
