Two blocks, with masses *m*_{A }and *m*_{B}, 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 *f *(revolutions per second) on a frictionless horizontal surface at distances *r*_{A }and *r*_{B }from the post. Derive an algebraic expression for the tension in each rod.

Step 1

Let T_{A} and T_{B} 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, ...
