1. A single span beam having an unsupported span of 20m carries a uniform load of "W" kN/m throughout its span. The beam has a cross section of 150 mm x 600 mm. Allowable bending stress of the wood is F, - 12.4 MPa with a modulus elasticity of 13800 MPa. a. Compute the allowable bending stress with the size factor adjustment. b. Compute the allowable bending stress with slenderness factor adjustment. c. Compute the "W" that the beam could carry.
