An alloy to be used for a spring application must have a modulus resilience of at least 0.72 * 106 J/m3 (0.72 * 106 Pa). What must be its minimum yield strength (in MPa) ? Assume that the modulus of elasticity for this alloy is 101 GPa.

A spherical soap bubble with a surface-tension of 0.005lbf/ft is expanded from a diameter of 0.5 in to 3.0 in. How much work, in Btu, is required to expand this bubble

A heat pump cycle operating at steady state receives energy by heat transfer from well water at 10oC and discharges energy by heat transfer to a building at the rate of 1.4x105 kJ/h.

The following information is available for a seeded 5-day BOD test conducted on a wastewater sample. 15 mL of the waste sample was added directly into a 300-mL BOD incubation bottle and then 285 mL of dilution water was added to fill the bottle.

A piston-cylinder assembly contains 5 kg of air, initially at 2.0 bar, 30 C. The air undergoes a process to a state where the pressure is 2 bar, during which the pressure-volume relationship is pV1.5 = constant. Assume ideal gas behavior for the air.

A low-temperature physicist wishes to publish his experimental result that the heat capacity of a nonmagnetic dielectric material between 0.05K and 0.5K varies as A√ T + BT^3 As editor of the journaL should you accept the paper for publication?

Consider an electric motor with a shaft power output of 20 kW and an efficiency of 88 percent. Determine the rate at which the motor dissipates heat to the room it is in when the motor operates at full load.
