A 40 mm diameter hole is drilled 3 m deep into the steel shaft. When the two torque are applied, determine (a) the maximum shear stress in the shaft: and (b) the angle of rotation of the free end of the shaft. Use G= 83GPa for steel.
Two forces are applied to the pipe AB as shown. Knowing that the pipe has inner and outer diameters equal to 35 mm and 42 mm, respectively, determine the normal and shearing stresses at (a) point a, and (b) point b
Water is being pumped from a large lake to a reservoir 30 m above at a rate of 5x10-3 m3/s by a 12 kW (shaft) pump. If the irreversible head loss of the piping system is 8m, determine the mechanical efficiency of the pump.
Advanced Stress Analysis
which of these two processes will produce the largest amount of work? (You must provide a full explanation for your choice).
assuming that the solid shaft has been replaced by a hollow shaft of the same cross-sectional area and with an inner diameter equal to half of its own outer diameter.
In the gear-and-shaft system shown, the shaft diameters are dab= 2 in. and dcd=1.5 in. Knowing that G = 11.2 x10^6 psi, determine the angle through which end d of shaft cd rotates.
determine the designe power. An output speed of 175 RPMis specified. Determine: a) number of teeth on the small sprocket, b) number of teeth on the large sprocket, c) lubrication type required, d) the required length of chain (in inches) if the ce..
If I take measurements using a Pitot Tube and get results for pressures Horizontal In, Horizontal Out, Vertical In, and Vertical Out all in inches of mercury. How do I take these pressures and determine a Velocity using Bernoullis equation?
The diffusion constant (Do) and activation energy (Q) of C in BCC Fe is 0.01 cm2/sec and 80kJ/mol respectively. In FCC Fe, the values are 0.21 cm2/sec and 148kJ/mol. At exactly 910oC these two phases can co-exist.
A refrigerator with a COP of 3 removes 1.5 kW from the cold space at -9 °C while rejecting heat to the kitchen at 22 °C.
For a combined turbine-generator efficiency of 83%, determine the net electric output. Disregard the effect of the KE correction factors.
Air enters an adiabatic compressor at 0.1 kg/s, 100 kPa, 25 °C and exits at 700 kPa. (a) Draw a schematic of the system. Determine (b) the minimum power input (kW) and (c) the entropy generation rate (kW/K)
