A uniform rod of length L and mass M is ...

A uniform rod of length `L` and mass `M` is free to rotate about a frictionless pivot at one end. The rod is released from rest in the horizontal position. What are the initial angular acceleration of the rod and the initial linear acceleration of the right end of the Rod ?

Text Solution

Verified by Experts


`tau_(o)=mgL/2=I_(0)alpha=(ML^(2))/(3)alpha`
`alpha=(3g)/(2L)`
`a_(B)=Lalpha=(3g)/(2)`
