Which of the following can be calculated when given the radius of a wheel and the radius of an axle?
A. The effort force needed to move the wheel and axle.
B. The amount of resistance force the wheel and axle can overcome.
C. The mechanical advantage of the wheel and axle.
D. The increase in effort force.

Respuesta :

Possibly B, I believe because a radious is half a diameter

Answer:

C. the mechanical advantage of the wheel and axle

Explanation:

the ratio of the radius of a wheel to the ratio of an axle gives the mechanical advantage for that wheel and axle system

i.e Mechanical advantage = [tex]\frac{radius of wheel}{radius of axle}[/tex]

for example if the radius of a wheel is 70m and the radius of an axle is 35m, the mechanical advantage for that machine is

M.A = 70/35 = 2

This implies that the outpu force  is 2 times that exerted by the input force
