What is the mechanical advantage of a first-class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?

answer is 4


What lever would have more mechanical advantage than one with a resistance are of 3 inches and an effort arm of 6 inches?

A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.


What is the mechanical advantage of a first class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?

The mechanical advantage of a first class lever is calculated as the ratio of the effort arm to the resistance arm. In this case, the effort arm is 40 inches and the resistance arm is 10 inches, giving a mechanical advantage of 4:1. This means that the lever can multiply the input force by a factor of 4.


Which lever would have more mechanical advantage than one with a resistance arm of 3 riches and an effort arm of 6 inches?

A lever with a resistance arm of 3 inches and an effort arm of 1 inch would have more mechanical advantage as the effort arm is shorter than the resistance arm, making it easier to lift the load.

The distance from the ground to the floor of a trailer is 20 inches. The length of the ramp is 50 inches. What is the mechanical advantage of this simple machine?

The mechanical advantage of a ramp can be calculated as the ratio of the length of the ramp to the vertical height it spans. In this case, the mechanical advantage is 50 inches (length of the ramp) divided by 20 inches (vertical height), which equals 2.5. So, the mechanical advantage of this ramp is 2.5.
