Homework Help Overview

The discussion revolves around a moments question, specifically focusing on part ii) of the problem. Participants express difficulty in understanding the concepts related to moments and torque.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants inquire about the specifics of part ii) and express confusion regarding the links provided. Others suggest drawing free body diagrams to analyze the forces and torques involved. Questions are raised about the conditions under which force Q equals zero and the relationship between distance and force Q.

Discussion Status

The discussion is ongoing, with participants sharing their uncertainties and seeking clarification. Some guidance has been offered regarding the use of free body diagrams and the calculation of torque, but no consensus or resolution has been reached.

Contextual Notes

Participants mention a lack of clarity regarding the problem setup and the specific details of part ii). There is an indication that the original poster may not have access to all necessary information from the provided links.

Do you know the answer to (i)? If so, try drawing a free body diagram for situation (i), and one for situation (ii), you'll notice something about the net force and torque in each case.
 
not really
 
When is force Q = 0?
Why does it decrease as he walks away?
 
i don't know. i just don't get moments.
 
Maybe you should read up on it a little. The hints they give you are pretty helpful.

Think about calculating torque around a point that will yield a simple equation and then use a couple of those equations to get an expression for Q.
