Question

Transcribed Image Text: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. Solve this
problem by balancing forces and torques, and applying the principle of
virtual work.
