How many trips would one rubber-tired herrywampus have to make to backfill a space with a geometrical volume of 5400 cubic yard? the maximum capacity of the machine is 30 cubic yard (heaped), or 40 tons. the material is to be compacted with a shrinkage of 25% (relative to bank measure) and has a swell factor of 20% (relative to bank measure). the material weighs 3,000 lb/cu yd (bank). assume that the machine carries its maximum load on each trip. check by both weight and volume limitations.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
