- A P = 10 kip 1.5 ft B C 2 ft The bars in the structure to the left are pinned and have circular cross-sections. The diameter of the cross- section is 1.5 inches. The bars are made of steel, which has an elastic modulus of 29,000 ksi. A point force of 10 kips is applied at point C, as shown. What is the change in length of member BC? Is the bar getting longer or shorter?arrow_forwardThe simply supported beam consists of a W21 × 44 structural steel wide-flange shape [E = 29,000 ksi; I = 843 in.4]. Assume that the support at D can provide resistance either up or down. For a loading of w = 7.8 kips/ft, determine:(a) the beam deflection vA at point A.(b) the beam deflection vC at point C.Assume LAB = 10 ft, LBC = 8 ft, LCD = 8 ft, LDE = 7 ft.arrow_forwardThe internal shear force V at a certain section of a steel beam is 79 kips.
