In winter season, he chemical observed a snow from a pavement that is being scooped up to a height of 40 ft by an endless bucket-scoop. and is then dropped into a container. He noticed that, at the highest point, the snow moves at 3 k’s. A total of 66 hp is needed to scoop snow at the rate of 100 lb’’s. Assuming a loss of 10% due to friction, calculate the percentage of tool work need to melt and break up the snow.

A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny
