Question:

A 108 in.-1ong beam AB is attached to the wall with a pin at point A and to a 68 in.€“long cable CD. A load W = 250 lb is attached to the beam at point B. The tension in the cable T is given by

where L and Lc are the lengths of the beam and the cable, respectively, and d is the distance from point A to point D, where the cable is attached. Make a plot of T versus d. Determine the distance d where the tension in the cable is the smallest.
