All circuits need three basic parts: an energy source, wires, and the object that is going to change the electrical energy into another form of energy called
a. load

b. form

c. frame

d. none of the above

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
