A heat pump has a coefficient of performance of 3.1 in heating mode. If it requires 130 J of work per cycle, how much heat per cycle does it put into the hot reservoir? How much heat per cycle is pulled in from the cold reservoir? During one cycle, a refrigerator removes 480 J from a cold reservoir and discharges 780 J into its hot reservoir. What is its coefficient of performance? How much work per cycle does it require to operate? In a very mild winter climate, a heat pump has heat transfer from an environment at 13.1°C to one at 26.3 C. What is the best possible coefficient of performance for these temperatures?

Slope and Deflection

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 after loading.
