A truck has a wheel that has a radius of 60 cm. The axle that powers the wheel has a radius of 10 cm. What is the mechanical advantage of the truck wheel?

a. 1/6
b. 1/4
c. 6
d. 4

The mechanical advantage of a wheel and axle system is determined by the ratio of the radius of the wheel to the radius of the axle. In this case, the radius of the wheel is 60 cm and the radius of the axle is 10 cm.

The mechanical advantage is therefore calculated as:

Mechanical Advantage = Radius of Wheel / Radius of Axle

= 60 cm / 10 cm

= 6

So the mechanical advantage of the truck wheel is 6.

Answer: c. 6
