A simply supported steel shaft of length L = 37 in is loaded with a uniform distributed load w = 6.5 lbf/in and a point load PA = 350 lbf located at a distance a = 11 in from the left end. Using singularity functions, find the deflections at A and at midspan. Note the percent difference between these two values.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

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
