Homework Help Overview

The discussion revolves around a problem related to radial-transverse motion, specifically focusing on determining an angle in a scenario involving forces and acceleration. The original poster is uncertain about how to find the angle after calculating the force.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants suggest using free body diagrams and breaking down equilibrium equations into components to find the angle. Questions arise regarding the relationship between acceleration in this part and previous parts of the problem, as well as the implications of being on the verge of slipping.

Discussion Status

Participants are actively engaging with the original poster's attempts and providing guidance on how to approach the problem. There is a focus on clarifying concepts and exploring different interpretations of the forces involved.

Contextual Notes

There is mention of specific conditions such as the object being on the verge of slipping and the need to consider static friction in the analysis. The original poster's previous work and diagrams are referenced but not detailed in the discussion.

Hi Jason03,

You follow the same procedure as you did part a. At point B (right before it slips) you know the total acceleration (magnitude and direction.) What forces are acting on the object? What information does being on the verge of slipping tell you? From your free body diagram you can write the components of the forces; some of these will contain theta and you can then solve for theta. What do you get?
 
You say that I know the acceleration, so does that mean its the same as in part A?...and the condition right before it slips is when static friction is about to be overcome by the force of gravity.
 
Hi, Jason. It's been a while but I will try to get you started. I will assume that you have already drawn your FBD and KD for when the block is just about to slip. Breaking Equilibrium equations into radial and transverse components should be your next move. What do have so far?
