A load P is applied at the end of a rigid beam that is just sufficient to close the gap between the rigid beam and the top of the column (2) at C. Then, the load P is increased until 2 = 1230 . [a = 3 ft,b = 6 ft, c =3 ft, L = 4 ft, L = 3 ft, gap = 0.25 in.] (1) gap (2) L What is the strain in element (1) for the original load P, just sufficient enough to close the gap at C? 2600 950 2250 3210 5010
