Homework Help Overview

The problem involves determining the tension in three wires, with participants expressing confusion about the initial steps and the overall approach to the problem. The context appears to relate to forces and tension in a physics setting.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss resolving tensions into components and applying vector laws. There are attempts to relate net force to mass and acceleration, with questions about the correct equations to use and the role of acceleration, which is not provided.

Discussion Status

The discussion is ongoing, with some guidance offered regarding the need to resolve tensions into components before applying formulas. Participants are exploring different interpretations of the problem setup and the necessary steps to take.

Contextual Notes

There is mention of gravity being a factor, and participants note the absence of certain information, such as the value of acceleration, which complicates their attempts to formulate a solution.

Ok here the problem i need to find the tension of the three wires but I am very lost and don't know where to start or how to finish.

so for i got 32*98 = 313.6N
i don't know what to do next
can someone please lead me in the correct direction to solve the problem.

First thing you need to do is to resolve all the tensions into triangular forces i.e translate a vector so you can treat the three tensions as applying the triange law for vectors
[tex]\vec{ac}=\vec{ab}+\vec{bc}[/tex]
 
ok so i have Fnet=M*a

so for the tension on the rock i have a tension and a weight
soball
\/ t1

/\ t1

so would this be the correct equation to solve for T if it is what would the acceleration be because its not give or i don't think there is anyway to find it
T1=313.6 * A

Before even attempting to solve for T you must resolve each tension into it's components. Simply applying a formula here is almost useless.
I must also apologies for not being able to understand what exactly you mean by the diagram

A isn't given, but it's a safe bet to assume that gravity is present.
