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.

Step 1

Let TA and TB be the tension force acting in the rods.

Draw the free-body diagram of both the blocks and represent forces acting on it.

Step 2

Write the expression for centrifugal acceleration acting on both the blocks.

Step 3

Write the expression for Newton’s second law, ...
