The 137-kg industrial door with mass center at g is being positioned for repair by insertion of the 3° wedge under corner b. horizontal movement is prevented by the small ledge at corner a. the coefficients of static friction at both the top and bottom wedge surfaces are 0.56. calculate the rightward force p' which would remove the wedge from under the door. assume that corner a does not slip for your calculation of p', but then check this assumption; the coefficient of static friction at a is 0.62.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
