You have been asked to make a material selection for a cylindrical mechanical part. The cylindrical rod is 100 mm long and has a diameter of 10 mm. This part will experience tensile stress during its application. The maximum allowable elongation is 0.3 mm because of the space limitations in the mechanical assembly and it must not have plastic deformation. (a) If the applied tensile load is 30KN during operation, would you recommend any of the materials listed below? are candidates? Justify your choice(s). (20 points)

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
