A beam with the cross section shown in the figure carries a bending moment that causes the elastic region to extend 1.5 in. from the neutral axis. Determine the residual stress distribution after the bending moment has been removed. Use σyp = 40 ksi.
Repeat this experiment for all your fingers, repeating the test several times on each finger. Compute the average and the standard deviation. Then perform the test on other subjects. Discuss your results. Do you notice large variations in the resu..

air from a workspace enters an air conditioner unit at 30degc dry bulb and 25degc wet bulb. the air leaves the air
Also, What is the lowest possible delivery temperature generated by an adiabatic air compressor, starting with standard atmosphere conditions and delivering the air at 650 kPa (gage)? Sketch the process on a Ts diagram.
measure the velocity of air. If the deflection deflection (the vertical distance between the fluid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 kg/m3.
Determine the sidelighting workplace illuminances for a 20 ft long, 15 ft wide (deep), 8 ft high light-colored room with a 15 ft long by 5 ft high window. Assume that the direct sun plus clear sky illuminance is 3000 fc and the ground-reflected il..
a steel cylinder initially contains nitrogen gas at 200kpa and 25 c. the cylinder is connected to a suply line
Due to oxidation at very high tempera- ture, the wire emissivity is s = 0.80 when it burns out. The water vapor properties at the film temperature of 1209 K are pv = 0.189 kg/m3, cp,v = 2404 J/kg · K, vv = 231 X 10-6 m2/s, kv = 0.113 W/m · K.
At the proportional limit, a 30 mm wide × 12 mm thick bar elongates 2.0 mm under an axial load of 41.5 kN. The bar is 1.5-m long. If Poisson’s ratio (ratio between longitudinal and lateral deformations) is 0.33 for the material, determine:

Consider a sheet of an fcc metal that has a {110} texture. That is, a {110} plane is parallel to the plane of the sheet and a direction is parallel to the prior rolling direction.
Find the value of so that the ramp-error constant is 2. Determine the value of so that the maximum overshoot of the unit-step response is a minimum and the settling time is a minimum. Give the values of the maximum overshoot and the settling time...
