Determine the bending moment acting at each of the following locations: (a) x = 0+ m (i. e., just to the right of fixed support A) (b) x = 3.5– m (i. e., just to the left of B) (c) x = 3.5+ m (i. e., just to the right of B) (d) x = 6.0 m

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
