# A cantilever beam AB, loaded by a uniform load and a concentrated load (see gure), is constructed of a channel section. (a) Find the maximum tensile stress st and maximum compressive stress s c if the cross section has the dimensions indicated and the moment of inertia about the z axis (the neutral axis) is 3.36 in4 I 5 . Note: The uniform load represents the weight of the beam. (b) Find the maximum value of the concentrated load if the maximum tensile stress cannot exceed 4 ksi and the maximum compressive stress is limited to 14.5 ksi. (c) How far from A can load P 5 250 lb be positioned if the maximum tensile stress cannot exceed 4 ksi and the maximum compressive stress is limited to 14.5 ksi

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.
