Thank you so much sir love from india
I have studied engineering for 4 years but no one taught this concept as simple as you have taught thanks a lot ...

Thank you for your video. However, the problem is not correctly posed. It appears that you are restricting both the sag of C and the sag of D. We can restrict only one of the three sags (B or C or D) for this problem. Letting y_AC (vertical distance between A and C) = 1m, y_AD = 1.167 (D is actually above point A). This can be easily verified by taking moment about D for the segment DE. In that case, T_CD would be 44.4 kN.

If you choose to restrict both the sag of C and D, then you will have to make one of the applied forces unknown. Otherwise, there are more equations (10: 2 for each node) than unknowns (9: y_CB, T_AB, T_BC, T_CD, T_DE, Ax, Ay, Ex, Ey). Hope this helps.

the value of TCD =75914.33 N take jiont C SUM FY (TCDSIN(@)=24000 It gives 75914.33N sir

Thank you sir..your videos were very informative..But I failed to understand why can we take moment about any point in the cable while ignoring one part of the section?

how abou an example for when catenary is pulled horizontal by an arm? i want to have a maximum angle of 14 degrees, how can i calculate this? thanks for all your help and videos

Sir what will be shape of cable due to uniformly distributed load parabola or catenary.i think catenary but in answer parabola is given.plz clarify it.

What would happen if there is a load in Z axis, for example wind load. (you only know wind velocity). Can you please explain how you will solve in this condition

34000/36000 is not 3/4..in cable DE..you are out
