Two identical uniform sticks of mass m and length I are pinned together. They both make an angle with respect to the vertical. A massless string is connected to the bottom of one rod and perpendicularly to the other rod as shown in the figure below. Determine the tension in the string if the table, on which the sticks are located, is frictionless.

3.2 Sliding blocks with friction* Mass MA = 4kg rests on top of mass Mg = 5 kg that rests on a fric- tionless table. The coefficient of friction between the two blocks is such that the blocks just start to slip when the horizontal force F applied to the lower block is 27 N. Suppose that now a horizontal force is applied to the upper block. What is its maximum value for the blocks to slide without slipping relative to each other?
