Question
A bar of square cross-section is subjected to point loads of P1, P2, P3, and P4 as shown here. Find the magnitude of the force P3 necessary for the equilibrium, if P1= 130 kN, P2 = 230 kN & P4 = 180 kN. Also, determine the stresses in each section & the net change in the length of steel bar, where the respective side of a square and lengths are d1=55mm, L1=31 cm, d2 = 40mm, L2=38 cm, d3=55 mm & L3 =30 cm. Take E = 185 GPa.
The force P3 to make it to equilibrium in kN is
The Stress in section 1 in N/mm2 is
The Stress in section 2 in N/mm2 is
The Stress in section 3 in N/mm2 is and The total change in length in x10-3 mm is
