    Bless you! You explained a difficult problem for me so efficiently. You easily broke down what is needed to be done and few reminders of what's what. My teacher tried to explain a very similar problem and just mumbled and got lost in his explanation. I knew how to do each step before the video, I just didn't know how to put the knowledge together. Bless you!

    at 14:00 why did you put Fsin0 - 700sin15 =500 , shouldnt forces upwards = forces downwards? because when i was trying to solve i put Fsin0 + 500 = 700sin15

    • @1963rzr
      @1963rzr  7 ปีที่แล้ว

      The questions says that the RESULTANT force acts up. You add all of the forces (with their corresponding signs) and the Resultant must be equal to 500. What you did is considering the 500 as an additional force and not as a resultant

    At 47:39 isn't it Sinus instead of Cosine?? Or do you follow the rule X = Cosine Y = Sinus?

      yoenes pattyn nope, it is cosine (adjacent side)

    Thank you so much for your lectures! My only question is: at 0:12:44 you say that summation of forces in Y is 500 N, Then you say that vertical component of F equals F*sin and then write a equitation F*sin -700*sin(15)=500. I can't really get is since summation of forces in Y and F are the same vector here. I would really appreciate your answer!

    I think it's better when you solve it step by step not just solve right away because other viewers don't know how you get that 539.62N

    Sir, the first problem i think alfa should be 60 because 105+15+60=180 and it is the angles of a triangle, isn’t?

      Sorry i noticed that 15 is the angle of the force thank u soo much

    Mr. second problem resolve the f2 into components along u and v I did not understand how the angle be 70 I will be glad if explan to me

    • @の雪-m5f
      @の雪-m5f 3 ปีที่แล้ว

      the sum of angle in a triangle must be equal 180, so 180-65-45=70

    Thank you for your videos; they are very helpful! Wanted to ask you about dividing one equation by another in a system. I was always taught that you can only add/subtract both sides, multiply both sides or divide both sides by the same number; besides not dividing by zero are there any other rules dividing the whole equation by another?

    Did anyone have an issue with the first method vs the second method? for some reason my calculator wants to keep pumping out 43.23 degrees for theta. I do (500+700sin15)/700cos15, then multiply by inverse tan.
