Question

g) How does a door knob and an egg beater work as wheel and axle?​

Answer 1

Answer:

A force applied to the outer rim of a wheel creates greater torque on the axle than the same force applied to an axle without a wheel. ... The larger the wheel, the larger the mechanical advantage, and the easier it is to turn the axle. This is the type of wheel-and-axle system that a doorknob creates.
