A dog owner has hired you to build a custom diving board for his award winning diving dogs. You've determined the diving board will weigh 150 lbs. In the most extreme loading case, the owner will have two dogs at D & E. The dog at D will weigh 43 lbs, and the dog at E will weigh 88 lbs. You want to make sure the joints are strong enough to support that loading case.
So what do you get when you calculate out the reaction forces of A and B?
A) A = 230 lbs, B = 511 lbs
B) A = -230 lbs, B = 511 lbs
C) A = 230 lbs, B = -511 lbs
D) A = -230 lbs, B = -511 lbs
