A timber beam having a simple span of 6m carries a total load including its own weight of 15KN/m. It has a
width of 250 mm and a depth of 300mm. Used dressed dimension by reducing its dimension by 10mm. The
wooden section is made up of 80% Apitong.
Fb = 16.5 MPa
Ew = 7310 MPa
Fv = 1.75Mpa
a. Determine the maximum flexural stress of the beam.
b. Determine the maximum shearing stress of the beam.
c. Determine the maximum deflection of the beam.
