A stainless steel bar, 10 inch long and 3/8 inch in diameter, is loaded in tension and experiences an elastic stretch of 100 microns. What is the load acting on it, if its young's modulus is 28 million psi?
xerted on the shaft shown in the figure, which rotates at 1150 rev/min and supports a 10-kip bending force. Use a 1095 HR steel. Specify a diameter d using a design factor of nd = 1.6 for a life of 3 min. The surfaces are machined.
many bridge designs today contain simple geometrical components but are constructed into complex ways to ensure that
saturated water vapor is enclosed in a piston cylinder arrangement with a volume v initial 5 liters at a temperature
a curved nozzle assembly that discharges to the atmosphere is shown. The nozzle mass is 4.5 kg and its internal volume is 0.002 m^3. The fluid is water. determine the reaction force exerted by the nozzle on the coupling to the inlet pipe.
according to a recent article hot-air volumes must be large because air heated to 150 degrees fahrenheit over ambient
Explain what is meant by an overall heat transfer coefficient and explain what is mean by failing and what its effect will be on the value of the overall heat transfer coefficient.
a mass of 12 kg of saturated refrigerant-134a vapor is contained in a frictionless piston-cylinder device at 240 kpa.
If the filling is done rapidly, calculate the final temperature in the small cylinder, (a) assume that oxygen is an ideal gas with Cv= 5R/2 and (b) using accurate thermodynamic data for oxygen.
determine the energy loss that will occur if water flows with a velocity of 7fts through a gate vlave fully open. what
What is the velocity and rate of flow of the metal into the mold? Is the flow turbulent or laminar? (Pure aluminum density ρ = 2.7 g/cm3).
During the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the work input during this process. R(air)=287j/KgK
a curved nozzle assembly that discharges water to the atmosphere is shown. the nozzle mass is 4.5 kg and its internal
