Attached Figure / Diagram
A
7.5
B
15.5
C
30.0
D
60.0
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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
