Two identical uniform thin rods have been connected at right angles to form a ‘T’ shape. One end of a rod is connected to the centre of the other rod. Length of each rod is L. The upside down ‘T’ can swing like a pendulum about a horizontal axis passing through the top end (see fig.). Axis is perpendicular to plane of the fig. The speed of the meeting point of the two rods is `u = 2 sqrt(gL)` when it is at its lowest position. Calculate the angular acceleration of the ‘T’ shaped object when it is at extreme position of its oscillation.

Answer

`(sqrt935)/(34) (g)/(L)`
