Mechanical benefit of Wheel and also Axle = M.A = Radius that the wheel/radius of the axle = R/r. Together R > r, the MA that wheel and also axle is always greater 보다 1.
You are watching: What is the mechanical advantage of a wheel and axle
Wheel and axle is actually a form of lever. The distinction is that the initiative arm can rotate in a finish circle roughly the fulcrum, which is the center of the axle. Force used to the exterior of the wheel causes a greater pressure to be used to the rope that is wrapped about the axle. As shown in the figure, the best mechanical advantage is calculated by separating the radius that the wheel through the radius the the axle.
Any crank-operated machine is an instance of a wheel and axle.
In this post, we will see just how to calculation the mechanical advantage of the Wheel and also Axle.
What is the ‘wheel and also axle’?
The wheel and also axle is a simple machine that consists of a wheel attached to a strong cylindrical axle.
The radius of the wheel (R) is better than the radius the the cylindrical axle (r). The wheel and also the axle have a typical axis. Once these two parts rotate with each other a force is transferred from one come the other.

The wheel and also axle have the right to be perceived as a version of the bar where a driving force or initiative is applied tangentially to the perimeter that the wheel and also a load pressure is applied to the axle.
To rotate the thin rod-like axle a pressure needs to be used on the more comprehensive wheel fixed to the axle. A tangential force applied to the perimeter of the large wheel can exert a larger pressure on a fill attached come the axle, achieving a mechanically advantage.
Setting up a wheel and axle combination to discover out the MA of this simple machine
A cable is wound around the axle cylinder and a load is attached come one free end the this string.
During rotational equilibrium conditions, the rotating impact of the wheel is same to the rotating result of the cylinder. (now see figure 2 above)
⇒ minute of the wheel about the axis = minute of the axle around the axis⇒ p × R = W × r, wherein P is the effort, and also W is the load.⇒ W/P = R/rAnd, Mechanical advantage =load/effort=W/P= R/r
