4/95 Each of the identical steel balls weighs 4 lb and is
fastened to the other two by connecting bars of neg-
ligible weight and unequal length. In the absence of
friction at the supporting horizontal surface, deter-
mine the initial acceleration a of the mass center of
the assembly when it is subjected to the horizontal
force F 20 lb applied to the supporting ball. The
assembly is initially at rest in the vertical plane.
Can you show that ā is initially horizontal?
