Machines can multiply force through mechanisms such as levers, gears, or pulleys. These devices allow for the transfer and amplification of force to increase the output. By manipulating the arrangement and size of these components, machines can effectively multiply the input force to perform tasks that would be challenging with human effort alone.
Does not multiply energy. Work done or energy used (force * distance) remains the same at both ends. Force or torque can be increased or decreased depending on mechanical advantage. It can change the direction of the force or torque.
A machine can multiply force multiple times, depending on the design and components involved in its operation. Systems such as pulleys, levers, and gear mechanisms are all examples of how machines can multiply force to achieve a desired output. Each component within the machine contributes to the overall force multiplication.
When a machine increases force, it means that the output force is greater than the input force. This change is typically achieved through mechanisms like levers, pulleys, or gears, which allow the machine to amplify the force applied. The overall result is that the machine can exert more force than what is initially put into it.
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.
A simple machine like a pulley can multiply and change the direction of an input force. By using multiple pulleys in a system, you can create a mechanical advantage that amplifies the force applied.
The machine has to leverage the original force in such a way as to multiply it.

That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.

The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
