Question: 3 . ) Three solid bars, each with square cross sections, make up the axial assemuly shown. Two loads of P = 3 0 kN

3.) Three solid bars, each with square cross sections, make up the axial assemuly shown. Two loads of P=30 kN are applied to the assembly at flange B, two loads of Q=18kN are applied at C, and one load of R=42kN is applied at end D. Determine the normal force in each bar, specifying tension or compression. [Answer: NAB[:=66kN(C),NBC=6kN(C),NCD=42kN(C)
