The figure shows a schematic for a hydraulic jack. Lever AC is hinged at A. The upper valve at D is closed; the lower valve at D is open. The density of hydraulic ‡uid is 833 kg/m3. Make an estimate for the force required at C to hold the system in equilibrium. You may assume the lever is approximately horizontal, and you may neglect the weight of the platform on which the car is sitting. Be sure to include the assumptions you must make in order to obtain this estimate.

Transcribed Image Text:The figure shows a schematic for a hydraulic jack. Lever AC is hinged at A. The upper valve at
D is closed; the lower valve at D is open. The density of hydraulic fluid is 833 kg/m³. Make an
estimate for the force required at C to hold the system in equilibrium. You may assume the lever
is approximately horizontal, and you may neglect the weight of the platform on which the car is
sitting. Be sure to include the assumptions you must make in order to obtain this estimate.
