THE BEST THANK YOU: www.examsoluti...
Crazy stuff man. Love it. Love from 🇧🇩 Bangladesh
I'm really struggling with this part of physics but this video is really helpful, so thanks a lot :)
Clear & good stuff. Crazy that this is from 2012, already.
Time flies by
Maths is one of the few subjects that often transcends time.

Seriously 3 years passed already
You're welcome
Sorry, but I am confused by your question. I did convert all the forces to Newtons and to do that we multiply by g. g being 9.8
Difficult to say without seeing your working.
Minecraft curios approves!
i was afraid this video wasnt legit but thank God it's Minecraft Curios approved
Thank you Sir...the video is old but it amazing... understood the concept without any probs..(much better than my teacher).
Watching in 2019
Thanks for watching despite its age.
Hope you don't drop off to sleep!
We'd have to calculate the moment and force of that turning point!
Oh sorry, I know now! I done 4g*3, as opposed to 4g*4 !!!
It is. It is the only upward force supporting the downward forces of the weight of the plank and children
why is the contact force (R) not factored in for the kids on the bench?
Thanks a lot. It really helped me!
I got it , thank you , i made a mistake , but thank you anyway :)
sir, at 19:08, I took moments in a clockwise direction, and I got M= 11 kg, I dont know where I went wrong!
Shabaz Khan 5 years later this man still doesn't know... someone help him
I know it has been 6 years, you have gone through uni, settled in an apartment with the women you love, working a 9-5 you hate. But alas I finally relinquish the burden of this question from your shoulders. M(0)clockwise= 10g(1)+4g(4)-mg(2)=0. Which rearranges to m=13.
You must have input the value for g as 10 N that's the only way your answer can end up being 11kg
Sir , can we first convert all the forces to newtons so we don't get confused with g ? also we don't need to multiply it by 9.8 ?
I was also confused by the g, I wasn't sure what it meant or why he converted 10kg into 10gN. Have you found an answer for this, 9 years later?
@@PinkBroBlueRope Because 10gN is the force (Weight = mass x gravity (g)), while 10kg is just the mass.
@@Maxoplasm Thanks for replying. It might be better to just say that g in this context is 9.8
what program do you use
what did u divide b 27g to give 264.6N
You dont divide anything ,you multiply 27g by the gravitational field strength because thats what g stands for and the gravitation field strength is 9.8 ,so it would be 27(9.8) which is 264.6 newtons
Sir, why do we not take into account the contact force of the children? why do we not include those in the equation as well?
thank you so much, your work has helped me loadz!
+Eesha Irfan We are only interested in the forces acting on the plank. The contact forces you mention act on the children not the plank.
+ExamSolutions oh okay, thank you so much!
