Horizontal force on hinge is affected by moving the block farther away?

Click For Summary

Homework Help Overview

The discussion revolves around understanding the effects of distance on the horizontal force exerted by a hinge in a physics problem involving a beam and a mass. Participants are exploring the relationship between the distance of the mass from the hinge and the horizontal force component.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Some participants attempt to analyze the problem by considering the horizontal force components and suggest using symbolic representations to explore the relationship between distance and force. Others express uncertainty about how to determine the horizontal force at the hinge and question the adequacy of previous calculations.

Discussion Status

Participants are actively engaging with the problem, with some providing guidance on drawing free body diagrams and labeling forces. There is a focus on ensuring clarity in the representation of forces and equations, although no consensus has been reached regarding the specific calculations or interpretations.

Contextual Notes

There are indications of missing information regarding previous calculations, particularly concerning the horizontal force component. Participants are encouraged to clarify their diagrams and equations to facilitate further discussion.

Homework Statement
The block is now moved closer to end A of the beam. Assume that the beam remains
horizontal.
State whether this change will increase, decrease or have no effect on the horizontal
component of the force exerted on the beam by the hinge.
Relevant Equations
theory questions, i think it uses vectors

I can't see your attempt.

done!
 
Presumably you have already found the horizontal component of the force exerted by the beam on the hinge in a previous part that you do not show. Redo this using symbols with ##x## being the distance of the mass from the hinge. Examine the symbolic expression. What happens to the horizontal component when ##x## is reduced?

in the previous part, there are calculations for vertical components not horizontal
but how would the horizontal force be found? i dont know how
like the 17 cos 50 would be the horizontal tension of the rope... what about hinge, i have no idea about it...

done
took time as i had to draw it digitally again...
 
Please label all the forces in the diagram so that we can refer to them. Also post the equations that you get from saying that the net force on the beam is zero and the net torque on the beam is zero.

Do all that on your next post instead of editing the old one.

There is a subtle difference between a post and a thread :wink:
