b) Determine the speed of the motorcyclist at the instant the acceleration is .
c) Determine the magnitude of the acceleration at the instant the speed of the motorcyclist is .
d) Determine the maximum constant speed of the motorcyclist when the maximum acceleration is .
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.
Two m^3 of xenon(Xe) are contained in a closed rigid tank at 70 degree C and 2 bar. The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7
A motorists inflates the tires of her car to a gauge pressure of 180 kilopascals on a day when the temperature is -8.0 degrees Celsius. When she arrives at her destination, the tire gauge pressure has increased to 245 kilopascals.
What is the average velocity of the body for the time interval, t = 0 and the time that it crosses the X-axis?
A metal block, placed on a rough surface, is attached to a spring and is given an initial displacement of 10 cm from its equilibrium position. It is found that the natural time period of motion is 1.0 s and that the amplitude reduces by 0.5 cm in ..
If you were asked to perform an excavation contract competitively with limited data, what type of contract would you want and why?
The beam ABC of length L has two different moments of inertia (2I in AB, I in BC) and a constant elastic modulus E. It is fixed at point A has a roller support at point B and a load P at C. a. Sketch the deflected shape of this beam.
