CLO 2: The girder of a simple log bridge supports a wheel load W
acting at any position along the span. In addition, the weight of
one log and the planks it supports is equivalent to a uniform load
of 850 N/m acting on the log. Determine the maximum
permissible wheel load W (in kN) based upon an allowable bending
stress of 7.0 MPa.

CLO 2: The girder of a simple log bridge supports a wheel load W
acting at any position along the span. In addition, the weight of
one log and the planks it supports is equivalent to a uniform load
of 850 N/m acting on the log. Determine the maximum
permissible wheel load W (in kN) based on an allowable shear
stress of 0.75 MPa if the maximum shear stress on circular sections
is 4/3 of the shear force divided by the cross-sectional area.
