I noticed that if we rotate it AC 53.13 degrees putting it at x axis then summation forces along Y-axis we will be able to determine the tension at AB, final equation AB = 200sin36.87 = 120N
Hello Sylvester, that is great question and no you don't need to worry about 3D problems. I didn't get any 3D problems, and none of my students ever mentioned getting 3D problems. I hope this helps and thank you for watching. Please share my channel with your friends who might find it helpful!
enGENIEer thanks for the speedy reply. I’m a little over a year out of school but I just purchased the Lindberg civil fe practice book (first edition). I’m just gonna try to do as many as I can and use your videos as a solid basis to relearn this stuff.
When you were in college did they expect you to remember all the math teachniques you applied and physics teachniques you applied in all the examples you show from memory or were you allowed to use your notes and a formula sheet? I cannot understand how or why the professors would expect engineering students to remember and apply so much math and physics without notes, a calculator, and a formula sheet. I did not study engineering in college . I studied Liberal Arts at a community college and then I studied English at a four year institution.

or 200 cos53.13
Yes 200cos51.13 is one step and quick.
If we take EM at point C / all we need the perpendicular distance for ( Tab )which is 5
EMc = (200* 3 ) - ( Tab * 5 )
Tab = 600/5 >> 120 N
Thank you
so helpful
Great explanation!
Can you make a video for a non equilibrium condition?
Should I spend time reviewing 3D statics equilibrium problems? I remember these in school, obviously a lot more math involved.

Are you just stealing the problems from Engineering Pro Guides?lol
I actually don't even know what that is. I got that problem from statics book. All the problems in my channel are from my notes from college!

just use a calculator , much faster
Hi Arman! Yes, you are right! It's much faster to do so. Thanks for sharing that with us.☺
