    Splitting Vector
AI Thread Summary
The discussion revolves around confirming calculations related to a vector splitting problem involving tensions T1, T2, and T3. The user calculates T1 as 452.6N based on the vertical component equating to the weight of the mass. For T3, the vertical component is set equal to the weight, leading to a calculated value of 653.3N. Substituting these values into the equation for T2 results in a final tension of 748N. The user seeks validation of these calculations to ensure accuracy in solving the problem.

a little help pleasezz

i'd like just some confirmation on my answers and thanks alot.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

Would Really appreciate the small help as am lost right now in this question,and would be so grateful.
 


Your answers look good.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
