Determine the x, y, z components of reaction at the ball-and-socket joint a.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
