From the figure shown, a truss is subjected to loads PI = 15 kN, P2 = 15 kN and P3 = 25 kN at joint C, D and E respectively. Use SI = 3 m; S2 = 4 m

Properties of diagonal members (2L75 x 75 x 6):

Ag = 1858 mm2

Fy = 248 MPa

rx = 22.9 mm

ry = 33.2 mm

Question:

a) What is the axial force in kN, in member DI?

b) What is the allowable stress in MPa, in member DI?

c) Calculate the allowable load in kN, in member DI.
