oil sg Lift cylinder Air = a x in y in z in The above diagram shows a hydraulic vehicle lift (details below). An air compressor keeps the oil pressure constant. What is the pressure drop (as a positive number) between the air and Point A? What is the air pressure if the pressure at point A is b psig? What is the weight of the lift and cylinder? Also, if the cylinder is required to lift a certain weight (which includes the weight of the cylinder); what would the pressure at Point A need to be? a = b (psig) = = X (in) = y (in) = z (in) = Lift Cylinder Diameter (in) Required Weight (lbs) = 0.88 1,048 36 320 63 - = 13,606
