A bridge girder AB on a simple span of length L = 20 m supports a distributed load of maximum intensity q at midspan and minimum intensity q/2 at supports A and B that includes the weight of the girder (see figure). The girder is constructed of three plates welded to form the cross section shown.
(a) Determine the maximum permissible load q based upon an allowable bending stress sigma = 140 MPa. Round to the nearest tenth.
qmax = ___ kN/m
(b) Determine the maximum permissible load q based upon an allowable shear stress Tau = 60 MPa. Round to the nearest tenth.
qmax = ___ kN/m
The Figure below shows a two-member truss supporting a block of weight W. The
cross-sectional areas of the members are 800 mm² for AB and 400 mm² for AC.
Determine the maximum safe value of W (kN) if the working stresses are 110 MPa
for AB and 120 MPa for AC.
