(15-56) An inventor claims to have built an engine that produces 2.00 MW of usable work while taking in 3.00 MW of thermal energy at 425 K, and rejecting 1.00 MW of thermal energt at 15 K. Is there anything fishy about his claim?
A concrete highway is built of slabs 18.0 m long (at 18 °C). How wide should the expansion cracks be (at 18 °C)
between the slabs to prevent buckling if the annual extreme temperatures are -37 °C and 54 °C?(the coefficient of linear
expansion of concrete is 1.20 x 10-5 oc-1)
When the pioneers were crossing the plains in covered wagons, a metal rim could be attached to a wooden wagon wheel by heating the rim to expand it and then placing it over the wheel before it cooled. The shrink-attachment would firmly hold the rim in place and strengthen the wooden wheel. Suppose a certain wooden wagon wheel has an outer circumference of 300.0 cm and that its iron rim has an inside circumference of 299.5 cm when it is at 15° C. To what temperature must the rim be heated so that it will just fit over the wheel?
