Thanks for the video At 7:20 In general ,When i try forces up=forces down It does not work if the moment taking in midpoint not side point like x,there is - value.this is make a big difference. So I think it is better to do clock wise method. Please let me know
you pick one point of reference then you can imagine the upward force on the left is clockwise as it would tilt clockwise, so downward force on the right is anti clockwise same way, downward force on the right of point of reference is clockwise and the opposite is anti clockwise
Everything! Old spec is fine, there isn’t much difference in content. Just be aware the new spec questions are more difficult. So that’ll get you 60% of the way. Also be aware that the meaning of terms for practical papers has changed so some old spec mark scheme answers won’t be acceptable now. Eg. Precision used to be used to mean resolution of an instrument, not any more.
@@nutshellphy also what is the ruling on rounding off the answers? should we round them off to a specific degree of accuracy or can we leave it in 4-5 sf?
Can you please make more videos like this solving questions for different topics that would be so helpful❗️❗️❗️
Thanks for the video

Please let me know
up and down only works for a pivot acting on a flat plane. situations like in this video arent simply up and down, they have components and angles so
Thank you for this, my paper 1 exam is in 2 hours :)
Good luck!!
Thank you is much this was really helpfull!!
15:50 How do you work out which one is clockwise or anti-clockwise?
you pick one point of reference
then you can imagine the upward force on the left is clockwise as it would tilt clockwise,
so downward force on the right is anti clockwise
same way, downward force on the right of point of reference is clockwise and the opposite is anti clockwise
thank you this is soo helpful!!
hey what papers should i practice for iAL edexcel since the new spec barely has any past papers ?
