    Thank you very much...I've been battling with moment calculations for the past two years..😢..thanks for making it seem as easy as pie... you're a good teacher 😊

    I tried to understand these concepts for the last 2 weeks in class but failed to understand but after seeing this video I understood it better.
    Thanks a lot sir it really helped me🫡🫡

    What do a physic teacher do if you throw a brick at him?
    He Duckett
    If you can understand this Mr Lovatt you are officially a BIS OG

    6:51 for this question I just did F X 3 = (2 X 80) - (4 X 60) + (6 X 90) and I got the right answer too (they both work out u can do + 2 X 80 with F so u basically take it to the other side of the equation or u keep - 2 X 80 on the same side)

    What abt this question
    A metre stick is balanced on a knife edge at its centre. When two coins each of mass 5gm are put on top of the other at 12cm mark, the stick is found to be balanced at 45.0cm. determine
    A.mass of the metre stick
    B.reaction of the support at 45cm pivot

    For the last question...I worked using the other distances from the pivot...not the perpendicular ones n still got the same answer howcome

    I have a question on the third equation, how did you get that 500 sir?

    • @yaraassaf851
      @yaraassaf851 3 роки тому +2

      1000-1500=500 then you’d get 2f=500 so you’ll divide and the final answer will be 250N/m

    A question why will we multiply 5m with 2m?

    • @DarkestBlixity
      @DarkestBlixity Рік тому

      Because we multpily the force by the distance from the pivot (the middle of the seesaw) not the distance between the forces

    Is it a must you write the clockwise moments=anticlockwise moments cause of you don't follow that you still get same answer

  • @Redeemed_Daughter
    @Redeemed_Daughter 5 місяців тому

    question 4
    Why did we include the 2m distance with 80N in the anticlockwise moment even they're on the right side of the pivot? I'm not even sure I'll get a response 😢

    • @ObiweFelix
      @ObiweFelix 10 годин тому

      You are going to consider only the distance to the pivot only not the total distance...I hope you understand my explanation.

    Question 3 - 2F = 500, where did 500 come from? and then 250?

    • @Shawncyaa
      @Shawncyaa 2 роки тому

      even im confused

    • @icantwu
      @icantwu 6 місяців тому

      2F = (1200+300) - 1000
      = 1500-1000
      =500.
      SO.. 2F = 500
      So F = 500/2 = 250.

    • @GabrielleGayleOfficial

      5:11 the F is not going clockwise it is a anticlockwise moment if you look closely you will see the 80N is going the same direction as F.

  • @taehyungishot3215
    @taehyungishot3215 2 роки тому

    for 3:51 why did times the force by 2

    • @ruthkalaba4378
      @ruthkalaba4378 2 роки тому

      Because 2 is the distance between the force F and the pivot. And to find moment we multiply the force and the distance

      @ObiweFelix 10 годин тому

      Check the movement of your wall clock (the movement of the minute hand of the clock is the clockwise moment)

    in the last question, shouldnt it be an inequality of 1000 x distance > F x distance?

    • @lovattphysics6366
      @lovattphysics6366  4 роки тому +3

      In reality, maybe, because the beam would have a mass. But in this question we are assuming everything is perfectly balanced and the beam itself has no mass (i know, it’s sometimes silly the assumptions we have to make!)

    The last question I didn't follow the perpendicular distance from the pivot but I got the same answer😂
    like: 1000×0.5=F×3
    500=3F
    F=500÷3
    F =167N😂
