A rectangular polypropylene [E = 6,200 MPa] bar (1) is connected to a rectangular nylon [E = 1,400 MPa] bar (2) at flange B. The assembly (shown in the figure) is connected to rigid supports at A and C. Bar (1) has a cross-sectional area of 4₁ = 1150 mm² and a length of I₁ = 1370 mm. Bar (2) has a cross-sectional area of 42 = 2950 mm² and a length of L₂ = 600 mm. After two loads of P = 4.5 kN are applied to flange B, determine: (a) the forces in bars (1) and (2). (b) the deflection of flange B. (a) F₁ = F2= (b) UB= apd i M A KN KN mm L₁ (1) P B L2 (2)
