Correct Answer: Option C

Explanation

Mechanical advantage of a machine = \(\frac{\text{LOAD}}{\text{EFFORT}}\)

In this case of a wedge, we can consider the dimensions given:

Load distance (height of the machine): 15 cm
Effort distance (movement of the effort): 0.5 cm

M.A = \(\frac{15}{0.5}\) = 30.0
