6-97. A log that is 0.6 m in diameter is to be cut into a rectangular section for use as a simply supported beam. If the allowable bending stress for the wood is σ allow = 56 MPa, determine the largest load P that can be supported if the width of the beam is b = 200 mm. h b- 0.6 m- P 2.4 m h b -0.6 m- P 2.4 m 2.4 m
