Here is my attempt:
Angular momentum of the rod about point D just before hitting the point D shall be: Σdm.x×v, where x is the distance from D and v is the velocity of that small mass.[Also taking mass of rod as M, length as L, and remember ω1 is the angular velocity of the rod about point C]...
I am sorry but I don't get it! What is the angular momentum of the rod about pin D just before it hits it (i.e., just before it hits the pin D)? I have tried taking the rod as a large number of very small masses and computing their momentum about pin D. But this doesn't give the correct answer.
Homework Statement
A uniform thin rod AB is equipped at both ends with the hooks as shown in the figure and is supported by a frictionless horizontal table. Initially the rod is hooked at A to a fixed pin C about which it rotates with a constant angular velocity w1 . Suddenly end B of the rod...
