The force applied by the women = 70 N
The mass of bucket and water together is = 6 kg
Total load = 6 × 10 = 60 N
Mechanical advantage (M.A.) = `"ЁЭР┐ЁЭСЬЁЭСОЁЭСС"/"ЁЭР╕ЁЭСУЁЭСУЁЭСЬЁЭСЯЁЭСб"= 60/70` = 0.857

In a block and tackle system consisting of 3 pulleys, a load of 75 kgf is raised with an effort of 25 kgf. Find:
- the mechanical advantage,
- velocity ratio and
- efficiency.
In following figure, draw a tackle to lift the load by applying the force in the downward direction.
- Mark in the diagram the direction of load L and effort E.
- If the load is raised by 1 m, through what distance will the effort move?
- State how many strands of tackle are supporting the load?
- What is the mechanical advantage of the system?
A block and tackle system has 5 pulleys. If an effort 0f 1000 N is needed in the downward direction to raise a load of 4500 N, calculate:
- the mechanical advantage
- the velocity ratio, and
- the efficiency of the system.
In following figure, shows a system of four pulleys, The upper two pulleys are fixed and the lower two are movable.
- Draw a string around the pulleys. Also show the place and direction in which the effort if applied.
- What is the velocity ratio of the system?
- How are load and effort of the pulley system related?
- What assumption do you make in arriving at your answer in part (c)?
