I A rod that falls while rotating from the end of a table

AI Thread Summary
A high school physics teacher in Korea poses a question about a rod that falls while rotating from the end of a table, seeking to find the final inclination and angular velocity under specific conditions. The discussion highlights the need for proper forum etiquette, suggesting that the question should be posted in the Homework Help section with relevant equations and attempts at a solution. Participants emphasize adherence to forum rules regardless of the poster's status as an educator. The conversation underscores the importance of structured problem-solving in physics discussions. Overall, the thread illustrates the balance between seeking help and following community guidelines.

Hi!
I am a high school physics teacher in Korea.
I have a question for you, a physics expert.

A rod that falls while rotating from the end of a table

A rod of mass m and length L is inclined by theta o (thera_o > 0) when the center of the rod is in contact with the end of the table, and the initial angular velocity is omega_o = 0. At this time, the rod was slightly pushed by an amount d in the longitudinal direction. The acceleration due to gravity is g, and the moment of inertia of the rod about the point of contact is I.

1. When the rod rotates without slipping at the point of contact and leaves the table, find the inclination theta_f and the angular velocity omega_f.

2. If the rod rotates slightly at the point of contact and then slips, find the angle theta_s at which the slip occurs.

3. When leaving situation 2, find the inclination theta_f and the angular velocity omega_f.

Even when posted by a teacher, it is a homework type question and should be posted in the appropriate sub-forum with an attempt to solve it.

Agreed.

@Kim Gi Hyuk -- Please repost this in the Homework Help, Introductory Physics forum and show the Relevant Equations and your Attempt at the Solution. Whether you are an instructor or not, you need to follow the PF rules (see INFO at the top of the page). Thank you.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
