An undeformed specimen of some alloy has an average grain diameter of 0.04 mm. You are asked to reduce its average grain diameter to 0.010 mm. Is it possible? If so, explain the procedure you would use to and the name the processes involved.

A 7.5-ft-long solid steel shaft (G = 11.2 x 106 psi) is to transmit 15 hp at a speed of 1500 rpm. The shaft is limited to an allowable shearing stress of 4.5 ksi and an allowable angle of twist of 4 degrees. Determine: a.

What is excess notation? What is twos complement notation? Why are they needed? In other words, why can't integer values be represented by ordinary binary numbers?

Air enters a 30-cm-diameter cooling section at 1 atm, 35°C, and 45 percent relative humidity at 18 m/s. Heat is removed from the air at a rate of 750 kJ/min.

The uniform crate has a mass of 50 kg and rests on the cart having an inclined surface. Determine the smallest acceleration that will cause the crate either to tip or slip relative to the cart.

According to the video, what are some of the effects of the increase in the use of automated tools for Loading Machine Operators? Check all that apply.

A gas flows through a one-inlet, one-exit control volume operating at steady state. Heat transfer at the rate takes place only at a location on the boundary where the temperature is Tb.

An uncharged capacitor and a resistor are connected in series to a source of voltage. If the voltage = 7.41 Volts, C = 11.5 µFarad, and R = 89.

The convection heat transfer coefficient for a clothed person standing in moving air is expressed as h 5 14.8V0.69 for 0.15, V, 1.5 m/s, where V is the air velocity. For a person with a body surface area of 1.
