1. Three large dogs (Labrador Retrievers: Barky, Chompers and Dancer) are on a bridge between two posts, A and E. The weights of three Labradors are: WB = 85 lb, Wc = 70 lb, and WD= 65 lb. The Labradors run off the bridge to swim in the river below. A very large dog (Saint Bernard) lopes onto the bridge. In order for the system of the three Labradors to be equivalent to the Saint Bernard, determine: (a) the required weight of the Saint Bernard (that is, what is the resultant force of the three Labradors), and (b) where must the Saint Bernard stand (that is, determine the distance, d, from point A.)
