# Question A simple span member is 6.65 m in length is made up of Apitong 185 mm x 270 mm wooden section, with an allowable stress based on 80% stress grade of 16.5 MPa in bending and tension parallel to grain. The beam carries a concentrated load of 18 kN at the center and neglecting its own weight. Weight of wood = 7.5kN/m3. The beam carries an axial tensile load of 192 kN.Bending and tension parallel to the grain = 16.5 MPa Modulus of Elasticity in Bending = 7310 MPa Compression parallel to the grain = 9.56 MPa Compute for the following:a) actual tensile stress if only tensile force is acting.b) interaction value for both bending and tensile stressc) ratio of the difference between its actual bending and tensile stress to the adjusted bendingstress for slenderness

A simple span member is 6.65 m in length is made up of Apitong 185 mm x 270 mm wooden section, with an allowable stress based on 80% stress grade of 16.5 MPa in bending and tension parallel to grain. The beam carries a concentrated load of 18 kN at the center and neglecting its own weight. Weight of wood = 7.5kN/m3. The beam carries an axial tensile load of 192 kN.
Bending and tension parallel to the grain = 16.5 MPa Modulus of Elasticity in Bending = 7310 MPa Compression parallel to the grain = 9.56 MPa Compute for the following:
a) actual tensile stress if only tensile force is acting.
b) interaction value for both bending and tensile stress
c) ratio of the difference between its actual bending and tensile stress to the adjusted bending
stress for slenderness
