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 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 ?

Draw a diagram of a block and tackle system of pulleys having a velocity ratio of 5. in your diagram indicate clearly the points of application and the directions of the load L and effort E. also mark the tension T in each strand.

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 block and tackle system of pulleys has velocity ratio 4. What will be its V. R. if the weight of the movable block is doubled ?

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 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 block and tackle system of pulleys has a velocity ratio 4. What is the value of the mechanical advantage of the given pulley system if it is an ideal pulley system?

A wooden block is placed on a table top. Name the forces acting on the block and draw a neat and labelled diagram to show the point of application and direction of these forces.

Draw a simplified diagram of a lemon crusher, indicating direction of load and effort.
