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.

Force analysis ON Off Set Cam.


You know Cam. It is generally used to open and close valve of IC Engine. In offset can the pointer is not towards the center. Now I do only one thing I dont change diameter of off set cam. You can understand by viewing my figure. So force by pointer (Stationary plate ) applied on cam ( without change of diameter, this is special cam.) You rotate that cam in any direction. The force applied by pointer (stationary plate) is same and constant. Now if you rotate cam (without change in diameter) in opposite direction, Stationary force applied by stationary pointer against to its motion, so you have to applied more force to rotate because you have to overcome the force applied by stationary pointer. But If you rotate cam in nearly same direction than it will help to rotate. who help (Stationary force applied by stationary plate or stationary pointer). Whom help ( Cam without change in diameter means pulley.)
To get idea read all post in this blog.

Mechanism that increase energy efficiency.


As shown in figure two pulleys can rotate about their axis. Stationary plate is simply supported on these two pulleys. Now the weight of stationary plate applied on each pulley in vertical downward direction is Mg/2. This Mg/2 will divided in two parts. One is tangential and second is towards the center. Tangential part will help to rotate pulleys and toward the center part will generate the friction.
