Question

A tie rod (1) and a pipe strut (2) are used to support a 50-kN load, as shown. The cross-sectional areas are A1 =650 mm2 for tie rod (1) and A2 = 925 mm2 for pipe strut (2). Both members are made of structural steel that has an elastic modulus of E=200 GPa.

a) Determine the axial normal stresses in tie rod (1) and pipe strut (2).

b) Determine the elongation or contraction of each member.

c) Sketch a deformation diagram that shows the displaced position of joint B.
