A 1 kg collar C slides without friction along the rod OA and is attached to rod BC by a frictionless pn. The rods rotate in the horizontal plane. At the instant shown BC is rotating counterclockwise and the speed of C is 1m/s, increasing at a rate of 1.2m/s^2. Determine at this instant, a) the tension n rod BC, b) the force exer

Consider the Hoover dam hydro-electric plant located in Arizona and Nevada. If the average lake level is 160 m above the turbine outlet, determine the minimum mass flow rate of water through the 17 turbines if the total power produced from all four turbines 2080 MW.

1. An impulse air turbine rotor with a blade speed (U) of 300 m/s is measured to have a relative rotor inlet velocity (W_1) of 750 m/s at an angle of 69 degrees and an outlet relative velocity (W_2) of 660 m/s. Th temperature and pressure in the rotor are 375 K, 0.83 bar. Calculate the rotor efficiency, rotational speed and powe

Question 4: An impulse air turbine has a total (on static) inlet pressure and temperature of 11,25 bar, 600 degrees K and exhausts to the atmosphere at 0.91 bar. The nozzle efficiency is 87% and its exit angle is 71 degrees. The rotor efficiency is 65%. If the blade speed if 190 m/s at the mean radius of 12cm, calculate the powe

Please help with the following problem.
Sketch the fully annotated velocity triangles for a Parsons turbine stage. Use your sketch to show that the specific work produced per stage is given as w_stage = (C_b)^2 [1 + 2(f/C_b)(cot(B_1))].
At a particular stage of a Parsons reaction turbine, the mean blade speed is 60 m/s an

A volleyball is spiked so that its incoming velocity of +3.8 m/s is changed to an outgoing velocity of -19 m/s. The mass of the volleyball is 0.38 kg. What impulse does the player apply to the ball?

A man kicks a 200g ball such that it leaves the ground at an angle of 30 degrees with the horizontal and strikes the ground at the same elevation a distance of 15m away. Determine the impulse of his foot on the ball. Neglect the impulse caused by the ball's weight while its being kicked.

Strain gauges are devices used to measure axial strain in a given direction. Assuming that you can attach as many string gauges as you wish (i.e. measure the strain in as many directions as you wish) at a point:
a) Can you measure all of the components of strain in the 3D strain matrix? Explain.
b) If so, what is the minimum

What is the flow rate in GPM (gallon per minute) for the water to run through each of the reversible turbine generator (6 of them} in Ludigton's hydro pumped system, assuming the average height at 300 ft and 312 MW power rating for each generator. How long will it take to drain the entire reservoir with a capacity of 27 billion
