Features
This apparatus set up on the lab bench using a stand base. The block and tackle can be expanded to  three pairs of pulleys and can support loads of up to 20N. the pulleys are mounted virtually friction free in ball bearings and for inclined plane, two forces are measured for various angles of inclination  using precision dynamometers. 
The fixed pulley, loose pulley and block are example of simple machine and represent the most  accessible introduction to the concept of work in mechanics. For the motion of incline an angle can be  describe most easily when the force exerted by the weight on the body
