An equilateral triangle is made from three mass less rods, each of length `l`. Two point masses m are attached to two vertices. The third vertex is hinged and triangle can swing freely in a vertical plane as shown. It is released the position shown with one of the rods vertical. Immediately after the system is released, find –
(a) tensions in all three rods (specify tension or compression),
(b) accelerations of the two masses

Answer

(a) `(5)/(4) mg, (mg)/(2), (3)/(4) mg`
(b) `(sqrt3)/(4) g`
