A member ABCD is subjected to point loads P1,P2,P3, and P4 calculate the force P3 necessary for equilibrium if P1, = 120 kN, P2, = 220 kN and P4, = 160 kN. Determine also the. net change in the length of the member. Take E = 200 GN/m². Calculate 40 mm x 40 mm 25 mm x 25 mm 30 mm x 30 mm A в P2 + 0.75 cm + im 1.2 m-
