A hand truck is used to move two barrels each weighing 80 lb. Neglecting the weight of the hand truck, find the vertical force P needed to maintain equilibrium when alpha = 40. Remember that you can decide which way the axes system goes. Would it be easier to run x along the horizontal axis of the page or along the axis of the hand truck when it comes to summing the moments?
