The force applied to the lever can be found by dividing the force exerted on the rock by the mechanical advantage of the lever. In this case, the force applied to the lever would be 200 N (800 N / 4).

What is a machine that applies force?

Mechanical Force is the force that is applied by a machine.


What does mechanical advatage mean?

Mechanical advantage refers to the factor by which a machine multiplies the force applied to it. It is calculated by dividing the output force of the machine by the input force applied to it. A higher mechanical advantage means that the machine is able to output more force than the input force provided.


Would increasing the length of a ramp increase mechanical advantage?

Increasing the length of a ramp does not change the mechanical advantage, as mechanical advantage depends on the ratio of the output force to the input force. The length of the ramp affects the distance over which the force is applied, but not the mechanical advantage itself.


What is the ratio of a machine's output force to the effort applied?

The ratio of a machine's output force to the effort applied is called mechanical advantage. It is calculated by dividing the output force by the input (applied) force. Mechanical advantage quantifies how much the machine can multiply the input force to achieve a greater output force.


What is the mechanical advantage of a fixed pulley?

A fixed pulley has a mechanical advantage of 1, which means it doesn't provide any mechanical advantage in terms of force. It changes the direction of the force applied without multiplying it.


The type of pully that does not have a mechanical advantage is?

The simple pulley is the type of pulley that does not have a mechanical advantage.


What two things you you need to know to calculate mechanical advantage?

To calculate mechanical advantage, you need to know the effort force applied to the machine and the resistance force it is able to overcome. By dividing the resistance force by the effort force, you can determine the mechanical advantage of the machine.


Actual mechanical advantage of a pulley?

The actual mechanical advantage of a pulley system is calculated by dividing the output force by the input force. It is the ratio of the load force being lifted to the force applied to lift it. This value indicates how much the pulley system amplifies the force applied.


What equation would use to calculate the ideal mechanical advantage of a wheel and axel if the imput force is applied to the axel?

The equation for calculating the ideal mechanical advantage of a wheel and axle when the input force is applied to the axle is: Ideal Mechanical Advantage (IMA) = Radius of Wheel / Radius of Axle where the radius of the wheel and axle are the distances from the center of rotation to where the force is applied.


What is the concept between mechanical advantage and ideal mechanical advantage?

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it. Ideal mechanical advantage is the theoretical ratio of the output force to the input force, assuming no energy losses due to friction or other factors. In reality, actual mechanical advantage is always less than ideal mechanical advantage due to factors like friction and inefficiencies in the machine.


What is the mechanical advantage of a machine that changes only the direction of applied force?

if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
