67.8 Ibm of air in a rigid container at 29 psia and 480 R absorbs 3.90172 kW'hr of energy from an electrical resistance heater. For this problem, account for variable specific heats, but do not interpolate. a) Assuming no heat transfer, determine: The final temperature: The final pressure: psia b) if the final pressure were 59.208 psia, determine: The final temperature:

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and af…
