(a) Mark in the diagram the direction of load L and effort E.
(b) If the load is raised by 1 m, through what distance will the effort move?
(c) State how many strands of tackle are supporting the load.
(d) What is the mechanical advantage of the system?
Answer –
(a)
(b) When the load is raised by 1 m, the effort moves through a distance = 1 × 5 = 5 m
(c) Total strands of tackle supporting the load are five in number.
(d) The mechanical advantage of the system is given by the following expression
M.A. = Load / Effort = 5T / T
Therefore, M.A. = 5
