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...

6. A capacitor with closely spaced circular plates of radius a is charged to potential p. Find E(z) at a point outside, on the axis at distance z from the center much greater than the plate separation. [Hint: The capacitor is equivalent to a thin disk-shaped electret, which in turn is analogous to a similar magnet. Use the known solution for the B-field in a related current configuration. Ans: E. p
