Two blocks, with masses mand mB, are connected to each other and to a central post by thin rods as shown in Fig. 5-41. The blocks revolve about the post at the same frequency (revolutions per second) on a frictionless horizontal surface at distances rand rfrom the post. Derive an algebraic expression for the tension in each rod.
