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 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.
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.
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.
How long is a bic mechanical pencil?
A standard Bic mechanical pencil is typically around 5.5 inches in length. Some models may vary slightly in size depending on the specific design.

How many inches is a mechanical pencil?
A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
Why can a machine with a mechanical advantage less then one useful?
The mechanical advantage is the number by which the input force gets multiplied. Butsometimes you want to multiply the distance, and you don't care about the force.The first example that comes to mind is the car's windshield wiper. The motor at the bottomswings a little lever a few inches from side to side. The mechanical advantage of the wiper armis much less than '1', so the force at the end of the blade is much less than the force of the motor,but it sweeps all the way across the window.The distance is multiplied by the reciprocal of (1 divided by) the mechanical advantage, so if themechanical advantage is less than 1, the output distance is greater than the input distance.In some applications, that's exactly what you want.
