The pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminum alloy [E = 61 GPa] with a cross-sectional area of A₁ = 810 mm². Bar (2) is a bronze alloy [E = 103 GPa] with a cross-sectional area of A2 = 470 mm². Assume L₁=2.4 m, L₂=3.1 m, a=0.7 m, b=1.9 m, and c= 1.1 m. All bars are unstressed before the load P is applied; however, there is a 5.8-mm clearance in the pin connection at A. If a load of P = 44 kN is applied at B, determine: (a) the normal stresses 0₁, 0₂, in both bars (1) and (2). (b) the normal strains &1, 82, in bars (1) and (2).

This question relates to structural analysis. Please give detailed answer.
State each of the structures as statically determinate, statically indeterminate, or unstable. If it is indeterminate, specify the degree of indeterminacy.
For the propped beam shown, lateral braces are provided at the supports and at the midspan. The factored beam weight is accounted for in the concentrated load. If Fy = 36ksi If Fy = 36 ksi, is a W18 × 50 adequate?
Classify each of the structures as statically determinate, statically indeterminate, or stable. If stable and indeterminate, specify the degrees of indeterminacy. If unstable, show the reasons. Also specify is Beam, Truss, or Frame.
