In a tensile test, a material fractured before necking. The true stress and strain at fracture were 630 MPa and 0.18 respectively.
(b) what is the length and diemeter at fracture? if the length (lo) and diemeter (Do)
specimen are 30 mm and 6 mm, respectively.

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

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false
