1. Sketch the influence lines for the vertical reaction at A, the shear at D, and the moment at D. 2. Draw the influence line for (a) the moment at B, (b) the shear at C, and (e) the vertical reaction at B. Solve this problem using the basic method of Sec. 6-1. Hint: The support at A resists only a horizontal force and a bending moment. 3. Draw the influence line for the force in (a) member KJ and (b) member CJ. Fonfon-fonPonfonLonT 4. Draw the influence line for the force in member CD. 13 m -2m2m
