The strength coefficient and strain hardening exponent of a certain test metal are 40,000 lb/in2 and 0.19, respectively. A cylindrical specimen of the metal with starting diameter = 25 in and length = 3.0 in is compressed to a length of 1.5 in. Determine the flow stress at this compressed length and the aver-age flow stress that the metal has experienced during deformation.
A barge is 60ft long, 20ft wide, and 8ft deep. When empty, it weighs 210,000lb, and its center of gravity is 1.5ft above the bottom. Is it stable when floating in water?
Two materials A and B are tested and a stress-strain curve is plotted. Material B has a yield stress of 200 MPa and Material A has a Yield stress of 120 MPa. These materials have plastic Deformation occur at the same Yield strain %.
water is flowing at a velocity of 10ft/s and a depth of 10ft in a channel of rectangular section. find the change in depth and in absolute water level produced by a smooth upward step of 1 ft. a smooth downward step of 1 ft in the channel bed.
Derive an equation that allows you to compute the diameter of the drain hole for a desired steady water height in the tank for the design condition inflow and pumping rates.
