(e) Mechanical advantage

2. Raju pushes a table by applying a force 50 N. find the work done by this force if the

table is displaced 10 m along the path.

3. The mechanical advantage of a machine is 10. How much load it can exert for the

effort of 4 kgf ?

plz plz plz ​

Answer 1

Answer:

see explanation

Explanation:

work :In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.

energy : Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

simple machine : A simple machine is a mechanical device that changes the direction and/or magnitude of a force. In general, they can be defined as the simplest mechanisms that use leverage (also called mechanical advantage) to multiply force.

complex machine : A complex machine is a machine made up of two or more simple machines that make your work easier to do. There are six simple machines from which all complex machines are made. They include: The lever. The inclined plane.

mechanical advantage : Mechanical advantage, force-amplifying effectiveness of a simple machine, such as a lever, an inclined plane, a wedge, a wheel and axle, a pulley system, or a jackscrew. ... In practice, the actual mechanical advantage will be less than the theoretical value by an amount determined by the amount of friction.

2) work done = f × d

50×10 = 500

3) ma = fo/fa =10/4=2.5
