Question 1 (5 points) Consider the figure below where the finished dimensions are shown. The V-block is manufactured from cast iron. Because hot metal occupies a greater volume than cold, a wood pattern is made using a shrink rule of 0.250" per foot for the green sand casting. A 7.0% allowance on the finished shape is given to cover extra stock for finishing all faces, and a 4.0 degree draft allowance is made on the vertical sides for pattern removal. The casting does not include the 1/4" X 1/2" slot on each side as these are machined into the block later. The as-cast material has a density of 0.29 Ib/in3 and cost $0.12 per lb, but 40% of the charge is remelted metal that has a cost of $0.08 per lb. Calculate the area of the bottom face of the casting pattern. DIMA 8.00 DIMB 3.50 DIM C 2.50 DIM D 1.25 DIME 0.50 CIND 1. be DRE
