A house has a black tar, flat, horizontal roof. The lower surface of the roof is well insulated, while the upper surface is exposed to ambient air at 300K through a convective coefficient of 10 W/m2-K.

The two boxcars A and B have a weight of 20000lb and 30000lb respectively. If they coast freely down the incline when the brakes are applied to all the wheels of car A causing it to skid, determine the force in the coupling C between the two cars.

Describe the term Coefficient of Performance (COP) in relation to heating or cooling cyclic systems.

Let A→ = (150iˆ+270jˆ) mm, B→ = (300iˆ-450jˆ) mm, and C→ = (-100iˆ-250jˆ) mm. Find scalars r and s, if possible, such that R→=rA→+sB→+C→ has zero x and y components.
