Given: W10x39 rolled-steel beam supports a load P at the
midspan. Knowing that P = 45 kips, L = 10 ft.
For W10x39 rolled steel section,
Determine (provide in ksi):
(a) maximum value of the normal stress ơm in the beam
(b) normal stress at flange/web interface ob
(c) maximum shear stress at flange/web interface txy
(d) Radius of Mohr's circle
(e) maximum value of the principal stress omax at the junction of the flange and web
d = 9.92 in.,
b, =7.99 in.,
