Mechanical Advantage of a Wheel and Axle Quiz

The formula to calculate the mechanical advantage of a wheel and axle is given by: $MA = rac{R}{r}$, where $R$ is the radius of the wheel and $r$ is the radius of the axle.

The mechanical advantage of the wheel and axle in this case is $MA = rac{10}{2} = 5$. Therefore, the mechanical advantage is 5.

If the radius of the wheel is doubled, the mechanical advantage of the wheel and axle will also double. This is because the mechanical advantage is directly proportional to the ratio of the radii of the wheel and the axle.

<p>The placement of the fulcrum affects the mechanical advantage of a lever system. If the fulcrum is closer to the load, the mechanical advantage is increased. If the fulcrum is closer to the input force, the mechanical advantage is decreased.</p> Signup and view all the answers
