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 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 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.

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 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 block and tackle has two pulleys in each block, with the tackle tied to the hook of the lower block and the effort being applied upwards. (a) draw a neat diagram to show this arrangement and calculate its mechanical advantage. (b) If the load moves up a distance x, by what distance will the fre end of the string move up ?

A block and tackle system has 5 pulleys. In ideal situation, (i) how is load L related to the effort E, and (ii) how is the distance de moved by effort related to the distance d, moved by load?

A block and tackle system has 5 pulleys. In ideal situation, (i) how is load L related to the effort E, and (ii) how is the distance de moved by effort related to the distance d, moved by load?
