The mechanical advantage of the machine shown above
7.5
15.5
30.0
60.0
Explication
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
