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. Symbolically (using the necessary variables) derive the three equations necessary to solve for the forces (Fi, F2, and F3) in the...
Problem 9.003 A rigid steel bar is supported by three rods, as shown in the figure. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rods (1) is 450 μm/m. Assume initial rod lengths of L1-2250 mm and L2-1700 mm. Determine (a) the normal strain in rod (2) (b) the normal strain in rod (2) if there is a 1-mm gap in the connections between the rigid...
The rigid bar is pinned at A and supported by two aluminum rods, each having a diameter of 1 in. and a modulus of elasticity Eal = 10(103) ksi. If the bar is initially vertical, determine the force in each rod when the 3.4 kip load is applied.

The rigid bar shown is supported by axial bar (1) and by a pin connection at C. Axial bar (1) has a cross-sectional area of A1 = 250 mm2, an elastic modulus of E = 200 GPa, and a coefficient of thermal expansion of α= 11.3 × 10-6/°C. The pin at C has a diameter of 40 mm. After load P has been applied and the temperature of the entire assembly has been increased by 10°C, the total strain in...
The rigid beam BD is supported by a smooth pin B, two circular rods at points C and D and is subjected to two concentrated loads as illustrated below.
