A 10 ft long rectangular ASTM A572 Grade 50 steel plate 1 in. by 12 in. in cross section is used as a hanger and subjected to a tensile load of 240,000 lb. The proportional limit of the steel is assumed to be 45,000 psi. Compute a) axial stress, b) axial strain, c) transverse strain, d) total axial dimensional change and e) total transverse (12 in. side) dimensional change.

Asmall 21 kilogram canoe is floating downriver at a speed of 1 m/s. what is the canoe's kinetic energy?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
