a) Cable ABC shown in the figure below has a length of 5m. Determine the position ‘x’ and the tension
developed in the cable ABC required for the equilibrium of the 100-kg sack. Assume frictionless pulley
at B and Neglect its size.
b) Suppose you are free to move the pulley through moving the hook at A up or down, and you are asked
to reduce the tension in the cable. What would you do? Explain and prove your answer by providing
sample calculations.
c) For the given configuration shown in the figure, explain the effect of cable length on the tension
produced in it. Prove your answer by sample calculations.
