Homework
A timber beam AB of length L and rectangular cross section carries
a single concentrated load P at its midpoint C. (a) Show that the ratio
Tm/Tm of the maximum values of the shearing and normal stresses in
the beam is equal to h/2L, where h and L are, respectively, the depth
and the length of the beam. (b) Determine the depth h and the width
b of the beam, knowing that L = 2 m, P = 40 kN, Tm = 960 kPa,
and om = 12 MPa.
