Question
a simpe wheel and axle is used to lift bucket of water out of a well. the radii of the wheel and axle are 20 cm and 4 cm, respectively. Determine,
1, velocity ratio
2, theoretical effort required to lift load of 30 N assuming no energy losses
3, the efficiency if the actual effort required is 10 N.
