Structural Engineering & Construction Situation 4 (PH)

PAST BOARD EXAM PROBLEMS Structural Engineering & Construction Situation 4 The truss shown is made from Guijo. The truss supports a vertical load P=20kN at C. Given the following allowable stresses for the grade of wood: Compression parallel to grain = 13.2 MPa Compression perpendicular to grain = 4.3 MPa Shear parallel to grain = 2.32 MPa 1. What is the axial stress of member AC? (1.32 MPa); 2. What is the minimum value of x? (75 mm); and 3. What is the minimum value of y? (20 mm). Credits: 1.
