Homework Help Overview

The problem involves a block hanging from a wall supported by two strings at different angles, requiring the analysis of tension forces in the strings.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the method of resolving forces into components using trigonometry, particularly when dealing with different angles for the strings. There is a focus on how to handle multiple tension variables.

Discussion Status

Some participants have provided guidance on using different tension variables for each string and suggested resolving forces into components. The discussion is ongoing with attempts to clarify the approach needed for the problem.

Contextual Notes

One tension value is given as 12 N, but the other tension remains unknown, leading to further exploration of the problem setup.

Homework Statement



So there's a block hanging from the wall and two strings are sustaining it, but they're at different angles.

Homework Equations


FAy= FACos(angle)
Fnet=ma

The Attempt at a Solution


Er, well, I can do this problem when the two strings are at the same angle (so they have the same tension), I just find the FAy using trig... but I don't know how to do it when the angles are different. Can anyone point me to some problems online or help? my textbook doesn't have anything.

You do it the same way, you just have two different tension variables, say T1 for string 1, and T2 for string 2.

Oh sorry, I forgot to write that one of the T is 12N and you have to solve for the unknown T.
 
Doesn't change anything. So now T1 = 12 N. You still solve it the same way. Resolve your forces into their components using trig, and sum them up in each direction. Use the equations you get to solve for what you are asked to find. Give it a try.
