Very good video. Thank you.
By solving your equation for sf= -144.5*x +726+484 and put x= 12.3
We get sf = 567 and here u are getting 561? Explain your sf at xx section which u calculate at last ...... Why value is difference and also while calculation we get last point or end point sf 37 which u got 43
Best... I am 2019 batch and U? M.Tech
