AI Thread Summary
The discussion centers on solving for T1 in a tension problem involving a chandelier, with participants sharing equations and solutions. The original poster struggles with their calculation, receiving incorrect results from their computer. They present multiple equations and seek verification for their final expression for T1. Another user confirms the correct approach involves multiplying both sides by sin(x2) to eliminate fractions and factoring tensions appropriately. The conversation highlights the importance of careful manipulation of equations in physics problems.

I need to solve for T1. the problem is a tension problem with a chandelier, but i have found all the equations to solve for the T1. I solve for T1 but the computer says its wrong. here are the equations and my answer. please help


(T1*cos(x1))/cos(x2) = (mg - T1*sin(x1))/sin(x2)

i keep getting

(cos(x2)mg)/2(sin(x2)cos(x1)+cos(x2)sin(x1)) = T1

x's are angles. someone pleas ehelp

well i got (0.5*mg*sin(x2))/cos(x1))=T1.
 
can anyone verify this because i only get one shot left
 
hmmm, I am sorry bout that, do you know what they mean by multiplicative factor?
 
i don't know but i haven't entered in your answer yet. i just want to make sure because i only have one chance left

someone please help me
 
i get:
T1 = mg / (cos(x1)*tan(x2)+sin(x1))

let me know if its correct.
 
AFG34, you got it right. thanks

cna i ask how you did that?
 
first you multiply both sides by sin(x2); this gets rid of the fraction in the right side, and the left side reduces to T1*cos(x1)*tan(x2). Then you just bring the Tensions to one side and factor them out.
