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?
a
6
b
12.5
c
17.5
d
0.17
e
37.5
To find the mechanical advantage of the wheel and axle shown below, we need to divide the radius of the wheel by the radius of the axle.
Radius of the wheel (r1) = 6
Radius of the axle (r2) = 12.5
Mechanical Advantage = r1 / r2
Mechanical Advantage = 6 / 12.5
Mechanical Advantage = 0.48
Therefore, the mechanical advantage of the wheel and axle shown below is 0.48.
Answer: d) 0.17
