Determine the required force P shown needed to maintain equilibrium of the scissors linkage when θ = 60°. The spring is unstretched when θ = 30°. Neglect the mass of the links.
The system consists of the two smooth spheres, each
weighing 3 lb and connected by a light spring, and
the two bars of negligible weight hinged freely at
their ends and hanging in the vertical plane. The
spheres are confined to slide in the smooth horizontal
guide. If a horizontal force F = 10 lb is applied to the
one bar at the position shown, what is the accelera-
tion of the center C of the spring? Why does the re-
sult not depend on the dimension b?
