SUMMARY

The discussion focuses on solving a vector splitting problem involving forces T1, T2, and T3. The user confirms their calculations, determining T1 to be 452.6N, T3 to be 653.3N, and subsequently calculating T2 as 748N. The approach involves breaking down the vectors into their vertical and horizontal components using trigonometric functions, specifically sine and cosine. The user seeks validation for their methodology and results, indicating a solid understanding of vector resolution.

a little help pleasezz

i'd like just some confirmation on my answers and thanks a lot.the link is the question.

well calling AB=T1, BC=T2 and BD=T3
recommend splitting vectors into components and equating them...

Vertical Component of T1 = T1*sin60 = weight of mass = 40*9.8=392N therefore T1 = 452.6N

now T2 = horizontal components of T1 & T3 = (T3*4/5)+(T1*Cos60)
now Vert. comp. T3 = T3*3/5 = Vert. comp. T1 = weight of mass =392N (from first line)
therefore T3=653.3N

now substitute T3 = 635.3N and T1 = 452.6N into the equation for T2 above and you find T2=748
