2. 2D Design (4 points): The Pawnee Department of Parks and Recreation has received alarming reports that their picnic tables might be unstable. Examine the picnic table design below (which weighs 50 lbf) and consider the case where one or more people sit on the same side of the table. You can assume that the weight of the sitters and the weight of the table both act at their centers of mass, given by GT and GM below. Do the Pawnee picnic tables need to be anchored to the ground? If so, how strong do the anchors need to be? (Hint: You will need to make appropriate and justifiable assumptions for the number of people and weight of each person). GM GT B 6 in.- -20 in. 20 in.
