A block and tackle system has the velocity ratio 3. Draw a labelled diagram of the system indicating the points of application and the directions of load L and effort E. A man can exert a pull of 200 kgf. If the effort end moves a distance 60 cm, what distance does the load move?

उत्तर
we know velocity ratio = `"d"_"E"/"d"_"L"`
and dE = 60 cm, velocity ratio = 3`
`d_L = d_E/("velocity ratio")`
= `60/3`
= 20 cm
