(a)Find the horizontal deflection at joint B produced by the 40-kip load in Figure P8.14. The area of all bars is shown on the sketch of the truss; E = 30,000 kips/in. 2 . (b) To restore joint B to its initial position in the horizontal direction, how much must bar AB be shortened? (c) If the temperature of bars AB and BC increases 80°F, determine the vertical displacement of joint C. ? t = 6.5 × 10 ?6 (in./in.)/°F. The rocker at support A is equivalent to a roller.
