Question
Transcribed Image Text:A 4.0-m-long simply supported timber beam carries two concentrated loads as shown. The cross-sectional dimensions of the beam are
also shown. Assume L1 = 0.8 m, L2= 1.6m, P = 5 kN, Q = 34 kN, a = 135 mm, b = 130 mm, c = 80 mm, and d = 460 mm.
(a) At section a-a, determine the magnitude of the shear stress in the beam at point H.
(b) At section a-a, determine the magnitude of the shear stress in the beam at point K.
(c) Determine the maximum horizontal shear stress that occurs in the beam at any location within the 4.0-m span length.
(d) Determine the maximum compression bending stress that occurs in the beam at any location within the 4.0-m span length.
