3) (40 pts) The EXTERNAL 35 kN force P is applied to the end of a 2 m long cantilever beam with the given cross section. The force acts through the shear center, forming an angle of 35 with the horizontal axis. The x, y axes pass through the centroid C. The y-axis can be assumed to coincide with the right- hand edge of the vertical section. Determine (a) the normal bending stress at Point A, (b) normal bending stress...

A bar of 15mm x 15mm square cross-section is machined so as to
reduce the thickness in a central region to 5mm, as shown in Figure
5. The bar is now subjected to a force F=2kN whose line of action
passes through the centroid of the original square section. Sketch
the distribution of stress in the reduced section and find the
maximum tensile stress. By what factor does this exceed the average
normal stress in the original section?
