2.54 The rigid bar AB of negligible weight is supported by a pin at 0. When the two steel rods are attached to the ends of the bar, there is a gap A between the lower end of the left rod and its pin support at C. After attachment, the strain in the left rod is 1.5 x 10-3. What is the length of the gap A? The cross-sectional areas are 300 mm? for rod AC and 250 mm² for rod BD. Use E = 200 GPa for steel. - 0.75 m -1.5 m - 2 m A FIG. P2.53, P2.54
