Selasi wants a shaft of 5/8 inches diameter to be used in his design project of which he is considering a design factor of 3. He hopes to get the same shaft size or 11/16 inch diameter shaft in the market for his design. So he decided to send his apprentice, Amuzu to the market. Unfortunately, when Amuzu went to the market, there were 1⁄2 inch, 9/16 inch, 3⁄4 inch, and 7/8 inch sizes available in the first shop. Amuzu decided to buy the nearest shaft size in the first shop instead of checking in the other shops where he could have gotten either 5/8 inch or 11/16 inch sizes.a. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 9/16 inch size shaft. b. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 3⁄4 inch size shaft.

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.
