A block and tackle pulley system has a velocity ratio 3.
i) Draw a labelled diagram of this system. In your diagram, indicate clearly the points of application and the direction of the load and effort.
ii) Why should the lower block of this pulley system be of negligible weight.
i)
The labelled diagram of the pulley system is as shown below:
ii) The lower block of this pulley system be of negligible weight to increase the efficiency of the system.
