When a polycrystal is elastically strained in tension, it is reasonable to assume that the strains in all grains are the same. Using this assumption, calculate for iron the ratio of the stress in grains oriented with parallel to the tensile axis to the average stress, σ 111/σ av = E111/Eav. Calculate σ 100/σ av.
A hydraulic lift must lift 7000 lbs using oil that is under pressure of 130 lbs/in^2. what must be the surface area of the lift cylinder?
To become acquainted with the operating principles of Hydraulic Pumps and Air Compressors. Disassemble each hydraulic pump. Neatly sketch or take a photo and label the parts of the pumps.
Design a ceiling diffuser. Air flows in the duct behind the diffuser and enters the diffuser at a pressure of 12.8psia, and a velocity of 200in/sec. The outlet of the diffuser is in the room, with atmospheric pressure of 14.5 psi. For the comfort of ..
for the stress element with sigmax 1400psi sigmay 600psi and shear 950 psi determine the average stress the maximum
Calculate the specific weight of toluene at a place where the acceleration of gravity is 32.2 ft/s^2or 9.81 m/s^2. Express your answer in both lbf/ft^3 and kg/m^3. Repeat this for Mars whre the acceleration due to gravity is 37.5% of that on Earth.
Nitrogen flows steadily through a pipe with a constant cross-section area of 6cm^2. The nitrogen enters the pipe at 500 kPa and 50 degrees Celsius with a velocity of 15m/s. The nitrogen leaves the pipe at 200 kPa and 25 degrees Celsius. Assume that t..

find: a) the pitch diameter of the pinion. b) the pitch diameter of the gear. c) the output torque of the gear. d) the minimum length of the key used to attach the gear?
Explain why an electric refrigerator, which transfers energy by means of heat from the cold food storage compartment to the warmer air in the room, is not an impossible "clauses device."
A line is represented by two end points (-1,0,0) and (2,0,0). The coordinate system is rotated 90 degrees about the y axis and then the orgin is moved to (2,2,2). What is the line in the new coordinate system? I need help on using this with homogeneo..
