Homework Help Overview

The discussion revolves around a force calculation problem involving two forces and their respective areas. The original poster attempts to calculate the force \( F_1 \) based on the given values but finds a discrepancy between their result and the book's answer.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the method used for calculating the forces and question the validity of the book's answer. There is a suggestion to start from a specific equation relating the forces and areas.

Discussion Status

Some participants are exploring the reasoning behind the calculations, while others express uncertainty about the problem's setup. The original poster claims to have resolved the issue independently, indicating a lack of consensus on the book's accuracy.

Contextual Notes

The original poster mentions that the problem was to solve for \( F_1 \), and there is an implication that the book's answer may be incorrect, though this is not universally accepted among participants.

[tex]F_1=x[/tex]
[tex]F_2=4000lbs[/tex]
[tex]A_1=1.5 in[/tex]
[tex]A_2=21 in[/tex]

So, i did:
[tex]F_1=1.5/21 * 4000[/tex]

Gave me 280 pounds.
My book, however, disagrees.
 
Physics news on Phys.org
Yes, but what is the problem??
 
Start with [tex]\frac{F_1}{A_1}=\frac{F_2}{A_2}[/tex]
 
never mind guys, i did it right. The book was wrong.

The problem was solve for X.

Thanks anyway!
 
I wish someone would give me 280 pounds!
