Problem

 A bench is to be designed for football players. It is to carry the load shown in Figure P7-64 approximating the case when 10 players, each weighing 300 lb, sit close together, each taking 18 in of the length of the bench. The bench is to be T-shaped, made from No. 2 grade hemlock, as shown with a 2X12 top board. Specify the required vertical member of the tee if the bench is to be safe for bending stress.
