For the in. thick L-shaped steel bracket shown in Figure P7–32 on page 432, show that the stress at.


For the  in. crowded L-shaped steel bracket shown in Figure P7–32 on page 432, likeness that the weight at the 90 re-entrant recess never converges. Try patterns delay increasing bulk of elements to likeness this while concoctting the acme highest weight in the bracket. That is, start delay one pattern, then furbish the entanglement environing the re-entrant recess and see what happens, say, following two furbishments. Why? Then add a coronal, say, of radius 1 2 in. and see what happens as you furbish the entanglement. Again concoct the acme highest weight for each furbishment.
