Answer the following question: Be sure to show all your work. Include formulae and units! EVERY TIME! Don’t forget to give relevant diagram.
The pressure inside an hydraulic piston is given by: P=3 X106 V-0.5, where P is in N/m2 and V is in m3.In the two minutes it takes to lift a piece of machinery, the volume of the piston expands from its initial value of 1.8 to 2.2 m3.
1. How much work is done in lifting the machinery?
2. What must be the power output of the motor lifting the piston?
