1.The bracket ABC can be supported in the eight different ways shown. All connections consist of smooth pins,rollers, or short links. For each case, answer the questions listed in Prob.4.59,and, whenever possible , compute the reactions,assuming that the magnitude of the force P is 100 lb.
2.A pumped storage power plant is to be designed for a flow rate of 6,000 cfs per penstock. The penstocks are 20 ft. in diameter, with a relative roughness of 0.008. The elevation difference between the two reservoirs is 340 ft. The head loss has to be less than 2% of the head available from the pump.
a.) Determine the allowable length of the penstock.
b.) Determine the HP of the pump required to pump the water.
