The pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminum alloy [E = 65 GPa] with a cross-sectional area of A₁ = 880 mm². Bar (2) is a bronze alloy [E = 119 GPa] with a cross-sectional area of A2 = 480 mm². Assume L₁=1.5 m, L2=2.0 m, a=0.6 m, b=1.8 m, and c=0.8 m. All bars are unstressed before the load P is applied; however, there is a 3.3-mm clearance in the pin connection at A. If a load of P = 52 kN is applied at B, determine: (a) the normal stresses 0₁, 02, in both bars (1) and (2). (b) the normal strains &1, E2, in bars (1) and (2). (c) determine the downward deflection VA of point A on the rigid bar.

Question 1. Specify the forces applied to the beams of the beam structure and the load patterns of the horizontal bar BDF. Question 2. Calculate the cutting force developed by the cutters shown in the picture, as well as the force applied to the hinge pin cutting force: (10kp = 100N)
True or False? When you/I cut through a rigid body or a truss that was previously in static equilibrium, then all of the members of that body or truss are still in equilibrium even though a section of that rigid body or truss has been removed from the structure. True or false?
