The mechanical advantage of a wheel and axle is the radius of the wheel divided by the radius of the axle.
What is the mechanical advantage of the wheel and axle shown below?
radius 15 cm
2.5cm
a
37.5
b
0.17
c
17.5
d
6
e
12.5
The mechanical advantage of the wheel and axle is:
15 cm (radius of wheel) divided by 2.5 cm (radius of axle) = 6
Therefore, the answer is (d) 6.
