The hydraulic jack in the figure is used to lift a 1000 kg mass load to a height y2 = 150 mm. The diameter of the lift cylinder is D = 50 mm. With this information, analyze the system and determine. a) The pressure, in bar. b) The diameter d of the hand pump cylinder, so that the driving force F1 is 50 N. c) If the maximum displacement of the pump piston for y1 = 20 mm, how many drives will it take to fully lift the load?

Question

The hydraulic jack in the figure is used to lift a 1000 kg mass load to a height y2 = 150 mm. The diameter of the lift cylinder is D = 50 mm. With this information, analyze the system and determine.

a) The pressure, in bar.
b) The diameter d of the hand pump cylinder, so that the driving force F1 is 50 N. c) If the maximum displacement of the pump piston
for y1 = 20 mm, how many drives will it take to fully lift the load? d) If you want to reduce the number of actuations by 2/3, keeping the diameter of the lift cylinder, D, the same actuation force F1, and the stroke y1, what geometric changes can be made in the system?
