ENGINEERING MECHANICS 2. FIND THE BAR FORCESa.) METHOD OF JOINTS
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 = 102 GPa] with a cross-sectional area of A₁ = 200 mm². Bar (2) is an aluminum alloy [E = 72 GPa] with a cross-sectional area of A₂ = 640 mm². All bars are unstressed before the load P is applied; however, there is a 2-mm clearance in the pin connection at A. Assume L₁ = 1880 mm, a = 1060 mm, b = 620 mm, c = 480 mm, and L₂ = 1270 mm. If a load of P = 71 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. (1) L₁ b tc B (2) D L2
2. (3 points) When loading is applied at a point on a body, the stress distributions at different cross sections are different. However, the stress distribution becomes uniform at locations far from the applied load. This is due to which principle? Name the principle.

Is it TRUE OR FALSE? 1. To analyze a statically indeterminate structure, an estimate of the member sizes must be made before the structure can be analyzed using an exact method. This is necessary because the analysis of a statically indeterminate structure is based on the elastic properties of the members. An approximate analysis of the structure will yield forces from which reasonable good initial estimates can be made of member sizes. If false why? Topic: Structural Analysis
Solve for external reactions and find internal forces in all of the members. Note: Read the question carefully and give me right solution according to the question.
