Transcribed Image Text:8.4-10 An overhanging beam ABC has a guided
support at A, a rectangular cross section, and sup-
ports an upward uniform load q = PIL over AB and
a downward concentrated load P at the free end C
(see figure). The span length from A to Bis L, and the
length of the overhang is L/2. The cross section has a
width of b and a height h. 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 D is o, = 38 MPa, determine the mag-
nitude of the load P. Data for the beam are L = 1.75 m,
b = 50 mm, h = 220 mm, and d = 55 mm.
