Out of 15 tested fuses 10 failed at 980, 380, 830, 350, 600, 710, 450, 920, 570 and 200 hours respectively. Use MS Excel to do this problem unless stated otherwise. a. Determine the Weibull parameters (η, β) using "Naïve Ranking"

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

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
