What is the relation between the load and the effort in the pulley system shown below:
L= 5E
E = 4L
L = E
L = 4E
L = 4T and E = T. Thus, L = 4E
Draw a neat labelled diagram showing a pulley being used to lift a load. How are load and effort related in an ideal situation?
The relation between load and tension in the following pulley system is
In fig shows a system of four pulleys. The upper two puleys are fixed and the lower two are movable.
(a) Draw a string around the pulleys.Also show the point of application and direction in which the effort E is applied.
(b) What is the velocity ratio of the system ?
(c) How are load and effort of the pulley system related ?
(d) What assumption do you make in arriving at your answer in part (c) ?
A block and tackle system has the velocity ratio 3. Draw a labelled diagram of the system indicating the points of application and the directions of load L and effort E. A man can exert a pull of 200 kgf. (a) What is the maximum load he can raise with this pulley system if its efficiency is 60% ? (b) If the effort end moves a distance 60 cm, what distance does the load move ?
