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 A₁ = 920 mm² and a length of L₁ = 1220 mm. Bar (2) has a cross-sectional area of A₂ = 2630 mm² and a length of L₂ = 570 mm. After two loads of P = 3.8 kN are applied to flange B, determine: (a) the forces in bars (1) and (2).

Then recommend the best option that provides the lowest displacement at node 1 by performing complete calculations to justify your recommendation. b. After the client approved your recommendation in (a), it was found that the displacements occurred at node 1 is still high. As a result, you are required to modify the truss design in order to reduce the displacement at node 1 by minimum 15% on a condition that modules of elasticity, and the force remain unchanged. Justify your recommendation. Las digit in Student ID O to 3 4 to 6 7 to 9 30° 36° 40° PI 5 kN 7 kN 8 kN
3 Q2 A beam, AB, of weight W= 50 N and length L = 0.8 m is supported by two springs, as shown in figure 2.1. The two springs have identical unstressed length; the spring on the left has a spring constant, k, = 200 N/m, while the one on the right has a spring constant, k₂= 100 N/m. A vertical and downward load, P = 40 N, is applied at a distance x from A. (i) Derive the value of x for which the beam will have a horizontal orientation at equilibrium. State and justify your assumptions and comment on your working. bewalls (ii) Assume the two springs have different unstressed lengths. In your own (exham Or words, show whether it is possible for the beam to have a horizontal orientation at equilibrium when one spring is stretched while the other spring is compressed.

The pin-connected structure shown in the figure consists of a rigid beam ABCD and two supporting bars. Bar (1) is a bronze alloy [E = 100 GPa] with a cross-sectional area of A1 = 270 mm2. Bar (2) is an aluminum alloy [E = 73 GPa] with a cross-sectional area of A2 = 630 mm2. All bars are unstressed before the load P is applied; however, there is a 4-mm clearance in the pin connection at A. Assume L1 = 1890 mm, a = 870 mm, b = 540 mm, c = 410 mm, and L2 = 1450 mm. If a load of P = 127 kN is applied at B, determine(a) the normal stresses in both bars (1) and (2).(b) the downward deflection of point A on the rigid bar.
