A push or pull which tends a system to change its state of rest or uniform motion. This needs a physical contact (unlike natural forces) between the system which applies the force and the system on which the force is applied.

How many times force is multiplied is the mechanical?

In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.


What is the mechanical advantage of a machine which only changes the distance of the applied force?

First of all, you cannot change the distance that a force acts throughwithout changing the force.But we see what you're getting at . . . you're asking what the mechanical advantage isif the force doesn't change on its way through the machine.The definition of the mechanical advantage is: (output force) divided by (input force).So if the input and output forces are equal, then the MA is 1 .

How mechanical advantage is expressed?

Mechanical advantage is expressed as the ratio of the output force to the input force in a mechanical system. It can be calculated by dividing the output force by the input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, while a mechanical advantage less than 1 indicates a reduction in force but a gain in distance or speed.


Which of these shows the correct way to calculate mechanical advantage?

Mechanical advantage is calculated by dividing the output force by the input force. The correct formula is: mechanical advantage = output force / input force.
