A body is subjected to a tensile stress of 1200 MPa on one plane and another tensile stress of 600 MPa on a plane at right angles to the former.
It is also subjected to a shear stress of 400 MPa on the same planes. The maximum normal stress will be
In many cases, we are concerned with free convection involving gases that are contained within sealed enclo- sures. Consider air at 27°C and pressures of 1, 10, and 100 bars. Determine the gure of meritdescribed in Problem 9.4 for each of these thr..
Check the applicability of the ideal gas model for- Water at 600 Fahrenheit and pressures of 900 lbf/in^2 and 100 lbf/in^2. Nitrogen at -20 Celsius and pressures of 75 bar and 1 bar
In FIGURE 5(a) the thermocouple is shown with an initial temperature the same as that for the ambient air, TA. It is then immersed into a tub of hot water at a constant temperature of Tw. Thus the applied step change in temperature is ΔT = Tw - TA..
The steam from the nozzles of a single wheel impulse turbine discharges with a velocity of 600 m/s at an angle of 20 degrees. The blade wheel rotates at 3000 rev/min and the mean blade radius is 590 mm
Describe one limitation of the Johnson Cook empirical model. Draw and label the phase diagram of carbon steel with up to 2.11% of carbon. Explain how to increase Martensite microstructure for hypo eutectoid steel.
Determine the power required, in hp, to overcome rolling resistance and aerodynamic drag when V is 55 mi/h.
A solid cone of radius R and vortex angle 2θ is to rotate at an angular velocity, ω .An oil of dynamic viscosity µ and thickness ‘t' fills the gap between the cone and the housing. Determine the expression for Required Torque.
Name two purposes and advantages of jigs and fixtures that are used as work holding devices
a walk-in cooler using a vapor compression refrigeration cycle is configured as shown below. the cycle uses cfc22 or
Steam at 550 lbf/in.2, 700oF enters a turbine operating at steady state and exits at 1 lbf/in.2. The turbine produces 500 hp. For the turbine, heat transfer is negligible as are kinetic and potential energy effects.
An insulated, rigid tank is divided into two equal parts by a partition. Initially, one part contains 6.06 kmol of an ideal gas at 155 kPa and 30C, and the other side is evacuated. The partition is now removed, and the gas fills the entire tank. Dete..
the solid a-36 steel shaft has a diameter of 0.75 inches. if it is subjected to the torques shown determine the max
