ICSE − Q & A

If the question says, draw the diagram of the "PULLEY SYSTEM" with V.R. = 4, then which diagram is to drawn-
1. Combination of 2 movable and 1 fixed pulley. (V.R. = 2^n, where n is the no. of movable pulleys)
2. A block and tackle system with 4 pulleys (where V.R. = no. of pulleys)?

Another question, why are there no hooks connected the upper block of the B&T system with the rigid support for even number of pulleys?
