Top suggestions for he C83400 red-brass rod AB and 2014-T6 aluminum rod BC are joined at the collar B and fixed connected at their ends as shown in (Figure 1). The cross-sectional area of each member is 1.75 in2 . Figure1 of 1 A 3-foot horizontal rod is attached at its left end 'A' to a vertical wall. Right end B of the rod is attached by a collar to another horizontal rod. The second rod is 2 feet long and has approximately the same diameter. The second rod extends to the right from the collar and is fixed at its right end C to another vertical wall. Part A If there is no load in the members when T1 = 50∘F , determine the average normal stress in the member AB when T2 = 125 ∘F . |
