There needs to be a correction in the formula for tangent length (1:56). Instead of Sine, there is a Tangent in the formula. Everything else is correct. My apology for this.
Chainage is the distance from one destination to another. If you want to find the chainage at PI then calculations steps depends upon the point of known chainage. I hope it clears your doubt.
I'm a bit unclear about your question, but based on what I understood, here is my answer: "I don't believe there is a need for chainage to calculate the deflection angle of the last chord. It solely depends on the length of the curve." Please let me know if this addresses your query.

We noticed that
good explanation, i wish u could do a video abt transition curve
Helpful🙏
Good video
how we find the chainage of intersection point ?

What if we're not given chainage at intersection point, how can we find the deflection of the last subchord?

@@CIVILSolved ooh okay, can I send you the question instead? Kindly assist me with your email address, it will shed more light... Kindly
@@hopenneyprincenney9854 Please check in the "About" section of this channel.
@@CIVILSolved okay, thank you so much sir
Please, how did you derived at the formula 90L/πR
TL=RxTAN deflection/2=64.30 this correct formula
T is 62.11 not 64.3
Please look at pinned comment.
Understanding the table is a problem for me, u just went writing answers without explaining how the various answers in the table was gotten
@@DanielBoakye-ic2cr which parameter in table you think need to be explained ?
