Draw a diagram of a block and tackle system of pulleys having a velocity ratio of 5. In your diagram indicate clearly the points of application and the directions of the load L and effort E. Also mark the tension T in each strand.
The velocity ratio of a single movable pulley is always 2.
The velocity ratio of a combination of n movable pulleys with a fixed pulley is always 2n.
The velocity ratio of a block and tackle system is always equal to the number of strands of the tackle supporting the load.
A metre scale of weight 50 gf can be balanced at 40 cm mark without any weight suspended on it.
