In the given figure, pulley systems containing one, two, and three pulleys. The number of pulleys in the type of system shown could obviously be extended to an arbitrary number N.
(a) Neglecting the weights of the pulleys, determine the force T required to support the weight W as a function of the number of pulleys N in the system.
(b) Using the result of part (a), determine the force T required to support the weight W for a system with 10 pulleys.
