The relation between load and tension in the following pulley system is
L = T
L = 2T
L = 3T
L = 4T
The load is balanced by the 2 Tensions in the 2 string parts.
Draw a neat labelled diagram showing a pulley being used to lift a load. How are load and effort related in an ideal situation?
A pulley system has a velocity ratio 3 and an efficiency of 80%. Draw a labelled diagram of this pulley system. Calculate :
(a) the mechanical advantage of the system, and
(b) the effort required to raise a load of 300 N.
