Transcribed Image Text:PROBLEM A
A timber beam 4 m long is simply supported at both ends. It carries a
uniform load of 15 kN/m including its own weight. The wooden section has a
width of 220 mm and a depth of 250 mm and is made up of 80% grade Apitong.
Use dressed dimension by reducing its dimensions by 10 mm.
PROPERTIES OF THE WOOD
Bending and tension parallel to grain = 16.50 MPa
Shear parallel to grain = 1.95 MPa
Modulus of elasticity in bending = 7.31 GPa
