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.

The weight of the cylindrical tank is negligible in comparison to the weight of water it contains (water weighs 62.4lb/ft3). The coefficient of static friction between the tank and the horizontal surface is s. (a) Assuming a full tank, find the smallest force P required to tip the tank, and the smallest s that would allow tipping to take place. (b) If the force P = 200 lb initiates tipping, determine the depth of water in the tank.
The bar ABC is supported by three identical, ideal springs. Note that the springs are always vertical because the collars to which they are attached are free to slide on the horizontal rail. Find the angle at equilibrium if W = kL. Neglect the weight of the bar.
The center of gravity of the nonhomogeneous bar AB is located at G. Find the angle at which the bar will be in equilibrium if it is free to slide on the frictionless cylindrical surface.
A safety valve on the top of a tank containing steam under pressure p has a discharge hole of diameter d(see figure). The valve is designed to release the steam when the pressure reaches the value Pmax If the natural length of the spring, is L and its stiffness is k, what should be the dimension ft of the valve? (Express your result as a formula for h.)
The high-pressure water cock is rigidly attached to the support at D. Neglecting the weights of the members, draw the FBD of the entire assembly and count the unknowns.

Problem-5: A Plunger is fitted to a vertical pipe filled with water. The lower end of the pipe is submerged in a sump. If the plunger is drawn up with an acceleration of 5 m/s², find the maximum height above the sump level at which the plunger will work without separation. Assume atmospheric pressure = 10 m water abs, and separation occurs at 2 m water abs. Take acceleration due to gravity as 10 m/s². [Ans. H₂ = 5.33 m]
