Rigid bar ABCD is loaded and supported as shown. Steel [E = 28500 ksi] bars (1) and (2) are unstressed before the load P is applied. Bar (1) has a cross-sectional area of 0.62 in.² and bar (2) has a cross-sectional area of 0.38 in.². After load P is applied, the strain in bar (1) is found to be 670 μe. Assume L₁=68 in., L₂=94 in., a-35 in., b=39 in., and c-22 in. Determine: (a) the stresses in bars (1) and (2). (b) the vertical deflection vp of point D on the rigid bar. (c) the load P.

I need help with this exercise from my homework. I have no idea about how to solve it. I need an step by step solving and explanation, please.
The geometry of the PQR plate after deformation (PQ'R) is shown with dotted lines. Calculate the shear unit strain at the Q 'corner.
1. Given: A truss shown below Find: (1) All the forces in 3 members and reactions at the supports (2) Is the member AC a zero-force member? If yes, explain which of the 2 conditions for zero-force members discussed in the class is satisfied. 100 N 3 4 B 4 m A 3 m
The cross-sectional area of each member of the truss is 1200 mm² and the allowable stresses are 100 MPa in tension and 80 MPa in compression. Calculate the maximum value of P the truss can carry. 5m 0.75 m 4 m 3 m B P
1. For the roof truss shown in Figure 3, determine the force present in ele- ment GH and in each element located to the right of GH. Also, establish whether the elements are in tension or compression. (I suggest you start from node M applying the method of nodes until you get to element GH) -2.4 m--2.4 m-1.2 m-2.4 m--2.4 m--1.2 m- 1.5 kN 1.5 kN 1.5 kN 1.5 kN D VI 1.5 kN 1 kN В 2.5 m E K 1 kN 1m H M F
if u don't know the answer skip it but try to take another expert please don't take it complexity please answer to another expert
analysis the truss using method of joints to find the internal forces. by steps please.
Draw the free body diagram. Do not round off between your solutions and box your final answer up to 4 decimal places
