Calculate the maximum Dead Load Deflection, Live Load Deflection and Long Term Deflection for the simply supported beam below. The dead load including its own weight is 1 k/ft. The live load is 0.7 k/ft. Assume 30% sustained live load for 3 years and a 20 ft span. Use 3000 psi normal weight concrete and 60,000 psi steel.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line
