a load of mass 10 kg is situated on a piston of diameter D1 = 140 mm. The piston rides on a reservoir of oil of depth h1 = 42 mm and specific gravity S = 0.8. The reservoir is connected to a round tube of diameter D2 = 5 mm and oil rises in the tube to height h2. Find h2. Assume the oil in the tube is open to atmosphere and neglect the mass of the piston.
Energy transfer in mechanical systems, A wheel is 800mm in diamiter and has a mass of 1000kg. on a horizontal surface without skidding, the vehicle accelerates uniformly at 0.5m/s^2 for 5 seconds.
a dry cleaning establishment buys 500 gal of carbon tetrachloride every month. as a result of the dry cleaning operation, most of this is lost to the atmosphere and only 50 gal remain to be disposed of.
A bug is crawling up the leg of a man on a train. The velocity of the bug relative to the man is 0.3 m/s k . The mas is waling from one side of a carriage to the other with a vlocity relative to the train of 1.2 m/s j.
