  • I wish I had this teacher my teacher doesn't even know what she's doing or how to teach

  • I go from wasting 2 seconds of my life watching a dumb Patrick video (Spongebob Squarepants) to learning an equilibrium problem... WTF??!! Oh, well, thanks for the lesson. I learned something new today. :D

  • NIce! i understood!XD

  • Thank you so much! My physics teacher goes way to fast with things like this...

  • or u can turn into a triangle and use the sine rule: a/SinA = b/SinB = c/SinC so that it goes T1/sin40=T2/sin40=Fg/sin100...­to get T1 u can go sin40x(Fg/sin100)=130.54N and T2=130.54 also quicker and much easier but a little tricky to get at first try :D doesnt mean you shouldnt use the one thats been shown coz if u wanna demonstrate to ur markers that you understand this concept then i recommend the video but if you just wanna answer the question quickly and easily...i recommend sine rule :D

  • thank you so much and I hope all your wishes come true :)

  • I understood it clearly.. I hope you can upload a lot of problem solving videos.. It can help a lot of students..

  • thank you so much. this helped a lot :D

  • u r the best physics teacher ever ever ever

    thank u so much

  • that is triangle force
