1.A rectangular tube has an outside dimensions that are 2in wide and 4in deep and a wall thickness of 0.25in. The tube is acted on by a bending moment of 12,000lb-in. A.)Determine the maximum tensile and compressive bending stresses.

B.) the bending stress 0.25in from the bottom of the tube

2.The 2kg block A and the 5kg block B are initially at rest on the inclined plane at 20 degrees. All surfaces in this system have a coefficient of static friction of 0.6 , and a coefficient of kinetic friction of 0.4 . Calculate the size of the mass ‘m’ so that block A slides relative to block B. block m is suspended over the wedge via pulley attached to B. A is at rest on top of block B
