A pulley system has a velocity ratio 5. Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram.
If a load of 10 kgf is pulled up by a distance of 2 m in 10 s, calculate the power developed by the effort (given g = 10 m `s^(-2)`).

A pulley system has a velocity ratio 5. Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram. If the efficiency of the system is 80% find its mechanical advantage.

A block and tackle system of pulleys has velocity ratio 4. Draw a neat labelled diagram of the system indicating clearly the points of application and direction of load and effort.

A block and tackle system has V.R. = 5. Draw a neat labelled diagram of a system indicating the direction of its load and effort.

A weight lifter lifted a load of 200 kgf to a height of 2.5 m in 5 s. Calculate :(i) the work done,and (ii)The power developed by him .Take g =10 N kg^(-1)

A pulley system has a velocity ratio of 4 and an efficiency of 90%, calculate: The effort required to raise a load of 300 N by the system.

A block and tackle system has velocity ratio 3. draw a labelled diagram of the system indicating the points of application and the direction of load L and effort E. A man can exert a pull of 200 kgf. (a) What is the maximum load he can raise with this pulley system if its efficiency is 60% ? (b) if the effort end moves a distance 60 cm, what distance does the load move ?

A coolie 1.5 m tall raises a load of 80 kg in 2 sec from the ground to his head and then walks a distance of 40 m in another 2 second. The power developed by the coolie is : (g = 10 m//s^(2))

A pulley system has a velocity ratio 3. draw a diagram showing the point of applicationi and direction of load (L), effort (E) and tension (T). It lifts a load of 150 N by an effot of 60 N. calculate its mechanical advantage. Is the pulley system ideal ? Give reason.

A crane lifts a mass of 100 kg to a height of 10 m in 20 s. The power of the crane is (Take g = 10 m s^(-2) )
