Two masses m are attached to two vertices of an equilateral triangle made of three massless rods of length l. A pivot is located at the third vertex, and the triangle is free to swing back and forth in a vertical plane. If it is initially released from rest when one of the rods is vertical (as shown), find the tensions in all three rods (and specify tension or compression), and also the accelerations of the masses at the instant right after it is released. Please show the work Thank you very much.
