For the state of plane stress depicted in the figure to the below:
(a) draw Mohr's circle.
(b) determine the principal stresses and show these on an element in the correct orientation relative to the x axis.
(c) determine the maximum shear stress and co-existing normal stress and show these on an element in the correct orientation relative to the x axis.
Show that the ?ow represented by f ¼ 10r cos y þ 40 ln r m2=s is an incompressible ?ow. Also, (a) Find the stream function c. (b) Find the pressure along the negative x-axis if water is ?owing and p ¼ 100 kPa at x ¼ -1.
Find the moment of inertia and natural frequency of a vertical cantilever pipe 12 feet tall with outer diameter of 4.5 inches and an inner diameter of 4.25 inches.
Many ventilation systems maintain a slightly higher pressure in a building than the outside pressure. If the pressure in your room is 0.1 psi than the outside pressure will you be able to open the door? How much is this force compared to your weight?..
a gas turbine unit has compressor inlet conditions of 100 kpa and 310 k. the compressor discharge pressure is 700 kpa
question 1approximate the torque and power necessary to rotate the inner 20 cm diameter cylinder shown in figure 1. sae
Say the arms each weigh 10% of the body weight (and have approximately uniform distribution of mass), and that each ring exerts only an upward force on each hand. What are the internal loads supported at the shoulders?
A balanced-cross-flow compact heat exchanger is required for an air heating system that processes 0.5 kg/s air. The inlet temperature for the hot water is 295 K, and the cold air enters at 270 K to be heated to 287 K. The inlet pressure for the hot w..

a gas turbine engine based on the brayton cycle uses air as the working fluid that produces 5mw net power output. the
A large plastic casting with thermal diffusivity 6.0*10-7 m2/s is removed from its mold at a uniform temperature of 150oC. The casting is then exposed to a high-velocity air stream such that the surface experiences a sudden change in temperature to 2..
water flows steadily through a 30-ft-long pipe from a hot water heater to a faucet. the velocity is 9 fts. at the
A piston-cylinder device has a volume of 0.1 cubic meters and contains 0.5kg of steam at 0.4 MPa. Heat is transferred to the steam until the temperature is 300 degrees Celsius
