A uniformly-distributed load wis supported by a structure consisting of rigid bar BDF and three rods. Rods (1) and (2) are 17-mm-diameter stainless steel rods that have an elastic modulus of E = 199 GPa. Rod (3) is a 23-mm-diameter bronze rod that has an elastic modulus of E = 101 GPa. Use a = 1.5 m and L = 3.1 m. For a load magnitude of w = 36 kN/m, calculate (a) the normal stress in each rod. (b)...
Your answer is partially correct. Try again. A load of P = 50 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 82 GPa, a = 15.7 x 10-6/0C] rods, and a solid steel [E = 197 GPa, a = 12.2 x 10-6/°C]. The bronze rods (1) each have a diameter of 29 mm and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod...
Problem 1) A load, P, is supported by a structure consisting of rigid bar BDF and three identical rods (cross-sectional area, A length, L; and elastic modulus, E), as shown. Load P is offset from the left bar by distance, c. Bars 1 and 2 are separated by distance, a; bars 2 and 3 are separated by distance, b.
