What is the formula to calculate the mechanical advantage of a wheel and axle?
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.
If the radius of the wheel is 10 cm and the radius of the axle is 2 cm, what is the mechanical advantage of the wheel and axle?
The mechanical advantage of the wheel and axle in this case is $MA = rac{10}{2} = 5$. Therefore, the mechanical advantage is 5.
How does the mechanical advantage of a wheel and axle change if the radius of the wheel is doubled?
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.
What are the two components of a lever system?
The two components of a lever system are the fulcrum and the load.
How is mechanical advantage calculated in a lever system?
Mechanical advantage in a lever system is calculated by dividing the distance from the fulcrum to the input force by the distance from the fulcrum to the output force.
How does the placement of the fulcrum affect the mechanical advantage of a lever system?
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.
