3 30 pound kegs are stacked on a dolley (2 on top of each other and the third on top of both of them opposite of the dolley back (they form kind of a triangle)). The dolley's base plate is 15 inches, and it's length is 60 inches, it forms an arcsin(4/5) angle off the floor to the right. The kegs DO NOT roll off each other. Each keg is 20 inches in diameter and 30 inches high. The dolley weighs 20 pounds, and it's wheels is 6 inches in diameter.
A) Calculate the force P to hold the dolley and kegs in the position that they are in now. NOTE- the force P may be acting in the opposite direction.
B) Calculate the force the dolley wheel exerts ON the floor. Assume no friction.
