13:47 it was wrongly mentioned the angle as 30 instead of 60 (i think it should be mentioned Rc cos 60 and Rc sin 60) , but corrected at equation. kindly clarify that.
can we take it theta angle as 60 degree from horizontal axis in first drwg?
Clearly explained
Sir doubt why you take horizontal force as sin teta its cos teta thana sir
No.,
The opposite side of theta is sin, adjacent side is cos.
Thank you sir
