Homework Help Overview

The problem involves analyzing the forces acting on a trunk being dragged up a ramp with a specified angle. The original poster is seeking assistance in determining the horizontal and vertical components of the pulling force applied at an angle to the ramp.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the potential approach of rotating the coordinate axis to align with the ramp. The original poster expresses uncertainty about this method and seeks clarification on how to arrive at the force components.

Discussion Status

The discussion is ongoing, with the original poster having calculated force components but unsure about the methodology. Some participants are offering insights into the problem-solving process, while others are requesting further details to provide more targeted assistance.

Contextual Notes

The original poster has mentioned achieving numerical results for the force components but is unclear about the steps taken to reach those results. There is a lack of explicit consensus on the approach to solving the problem.

Homework Statement


A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0, and the man pulls upward with a force of magnitude 381N whose direction makes an angle of 30.0 with the ramp.

Im in need of some help I can't seem to figure out how to get each component of the force I know each has its own force in the x and y

I would start off by rotating my axis so they match with the ramp axis, which I'm sure you have done in class, then figure out the gravitational force down the ramp and the pulling force up the ramp. If you want more help you will have to be more specific and show what part you are stuck on.
 
hmm actually no i never rotated the axis i couldn't figure out how to solve the problem. i ended up with the answers I am just trying to get an idea of how it was solved. I got 245N for the x components and 292N for the y

You must have done a lot of algebra then, but you ended up with the right answer (good if so)? Can I see what you did?
