Textbook Question
Chapter 8, Problem 8.4.10P
An overhanging beam ABC has a guided support at A, a rectangular cross section, and supports an upward uniform load q = PtL over AB and a downward concentrated load P at the free end C {see figure). The span length from A to B is L, and the length of the overhang is L12. The cross section has a width of A and a height A. Point D is located midway between the supports at a distance d from the top face of the beam.
Knowing that the maximum tensile stress (principal stress) at point Z> is tr, = 38 MPa, determine the magnitude of the load P. Data for the beam are L = 1.75 m, b = 50 mm, // = 220 mm, and d = 55 mm.
