570. A uniformly distributed load of 200 lb/ft is carried on a simply supported span. I the cross section is as shown in Fig. P-570, determine the maximum length of the beam if the shearing stress is limited to 80 psi. Assume the load acts over the entire length of the beam. Ans. 12.6 ft 6 in.- H 8in. Figure P-570 and P-571 571. For a beam with the same cross section as that in Prob. 570, plot the shearing stress distribution across the cross section at a section where the shearing force is V = 1800 lb. 8 in. 10 in.

PLEASE ANSWER PROBLEM 571
570. A uniformly distributed load of 200 lb/At is carried on a simply supported span. L
the cross section is as shown in Fig. P-570, determine the maximum length of the
bear if the shearing stress is limited to 80 psi. Assume the load acts over the entire
length of the beam.
571. For a beam with the same cross section as that in Prob. 570, plot the shearing stress distribution across the cross section at a section where the shearing force is
V= 1800 lb.
