### Stationary Force Can Be Utilized To Do Work. Before explaining I want to clear some basic things.
v=Velocity. Rate of change in the position of an object
v=dx/dt Meters/Second.
a=Acceleration.
a=Rate of change of velocity.
a=dv/dt =dx/dt2.Meters/second2
Because v=dx/dt
Force (F) = M*a=M*dv/dt=M*dx/dt2 Kg-meters/second2 or Newton.
Work=Force* Distance traveled Newton-Meter.
But what happen when force is stationary or can not travel and object can travel at less than 90` Angel with direction of force.
Answer is "Stationary or static force will help to move object." You can use static gravity force. or static hydraulic or pheumatic force. Becuse of force is static, you will not lose any Energy to rotate pulley.

See Figure

There are two pulleys can rotate about their respective axis. Stationary force (MG) applied on pulleys by stationary plate (stationary plate is simply supported on pulleys.). This MG is equally divided and applied on each pulley in vertical downward direction(MG/2). This MG/2 will divided in two parts. one is tangential (MG/2 * Cos (Alpha)) and second is towards the center (MG/2 * Sin (Alpha)). Tangential force will help to rotate pulleys. Towards the center part will generate friction.
Uses and Advantages:
1. It will decrease manufacturing cost.

2. It will decrease electricity Bill.

3. It will help to reduce green house effect.

4. It provides clean energy.

5. It is cheap and available at every place.

6. It can use for both linear as well as for circular motion also.

7. It will improve quality of people’s life by giving clean and cheap energy.

8. It will help to reduce carbon dioxide in environment.
