A uniform triangular plate is kept horiz...

A uniform triangular plate is kept horizontal suspended with the help of three vertical threads as shown. The sides of the plate have length `l_(1), l_(2)` and `l_(3)`. Find tension `T_(1), T_(2)` and `T_(3)` in the three threads. Mass of the plate is M.

Text Solution

Verified by Experts

The correct Answer is:
`T_(1) = T_(2) = T_(3) = (Mg)/(3)`
