1. A 10 inch long cantilevered beam has a 1” by 1” square cross section. The load at the end of the beam cycles from 0 lbs to 300 lbs. determine the stress.
2. Determine the slenderness ratio and column constant of a 38” long steel column that has a 1.5 inch per side square cross section. The column is made from AISI 1050 CD steel and is pinned on one end and fixed on another.
3. Determine the endurance strength for a 1.5” diameter machined shaft that is made from AISI 1040 CD steel. The shaft is subjected to rotating bending stress and should have a reliability of 99.9%
