10. A block and tackle system has the velocity ratio 3. Draw a labelled diagram of the system indicating thepoints of application and the directions of load L andeffort E. A man can exert a pull of 200 kgf. (a) Whatis the maximum load he can raise with this pulleysystem if its efficiency is 60% ? (b) If the effort endmoves a distance 60 cm, what distance does the loadmove ? |
