Given a set, weights, and an integer desired_weight, remove the element of the set that is closest to, but not greater than desired_weight, and associate it with the variable actual weight. for example, if weights is (12, 19, 6, 14, 22, 7) and desired_weight is 18, then the resulting set would be (12, 19, 6, 22, 7) and actual_weight would be 14. assume there is at least one value in the set that is less than desired_weight.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
