Homework Help Overview

The problem involves a wheel with a mass of 15kg and a radius of 1m being pulled by a horizontal force against a step that is 0.4m high. The original poster seeks assistance in determining the initial force required to turn the wheel over the step and the behavior of this force as the wheel rises.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster expresses uncertainty about how to approach the problem and requests a breakdown of the question. Some participants question the initial assumptions and setup, while others suggest geometric considerations, such as forming a triangle, to aid in understanding the forces involved.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some guidance has been offered, but there is no explicit consensus on the approach to take. The original poster is looking for clarity on the initial force and its variation as the wheel rises.

Contextual Notes

The question is part of a larger problem set, and the original poster has completed the previous parts, indicating a potential reliance on prior knowledge or context that may not be fully shared in this thread.

I have no idea how to attempt this question, please help me. Anyone.

The question : The diagram shows a wheel whose mass is 15kg and radius 1m being pulled by a horizontal force F against a step 0.4m high. What inital force is just sufficient to turn the wheel so that it will rise over the step? What happens to the size of this horizontal force as the wheel rises?

This question is the last part of a long question, I did all the other parts. Can someone just break this down?

Omg I knew IT! I should of made a triangle my father was trying to help me but he didn't listen!
 
I thank you so much, the .8m will be multiplied by the 150N
