The truss shown below is composed entirely of steel tubes (Oy,stens = Oy,comp = 200 MPa) having a circular cross section, with an outer diameter of 40 mm and an inner diameter of 30 mm. The truss is supported by a pin at A and a roller at E. Loads are applied at joints B, C, and D as 10 kN 8 kN 4 kN shown. BY 3 kN- D The support reactions are (axes shown): Ax = -3 kN; Ay = 8.87 kN; Ey = 13.13 kN 1.5 m (a) Determine the axial load in each member of the truss. State if the member is in A E tension or compression. F y 2 m 2 m (b) Solve for the overall safety factor with respect to yielding of the truss.
