Chapter 10, Problem 66P
Measured data for performance of the reaction turbines at Shasta Dam near Redding, California, are shown in Fig. 10.38. Each turbine is rated at 103,000 hp when operating at 138.6 rpm under a net head of 380 ft. Evaluate the specific speed and compute the shaft torque developed by each turbine at rated operating conditions. Calculate and plot the water flow rate per turbine required to produce rated output power as a function of head.

A single degree damped vibrating system is formed of a block of mass m = 7 kg, a spring of K = 100 N/m and a damper of damping constant C.
The initial position of the block is at x0 = 100 mm. The system was initially at rest. The figure below represents the variation of the displacement of the block with respect to time.
Determine the response of at t = 1s for x1 = 10 mm.
Select one:
x(t) = 13.227 mm
x(t) =-28.9637 mm
x(t) = 21.002 mm
x(t) = 45.4319 mm

A sign ABCD is constructed from 5 mm thick plate steel
(density p=8000 kg/m³) with the geometry shown in the
figure. The sign is connected to the wall by a pin at A and
also supported by member BE. Support member BE is also
constructed from 5 mm thick plate steel and is connected by
pins at B and E respectively. Determine the reaction forces
at A and E. Enter your answers in Cartesian components.
The weights of both the sign ABCD and member BE
should be accounted for in the calculation. Assume the pins
