Torque of a Couple - A Level Physics

- This video introduces torque and explains the torque of a couple for A Level Physics.
If you have two equally sized forces that act towards each other but are offset then you have a resulting moment but no resulting force. Because there are two forces we call this the torque of a couple. In order for an object to be both stationary and in rotational equilibrium, the forces acting on it must be equal in size, opposite in direction and acting through the same point.
Thanks for watching,

For those who don't understand 1:02 like I did for a split second.
M = F(d/2) + F(d/2) {initial}
M = F(d/2 + d/2) {factorise}
M = F(d) {add}
M = Fd {final}
Thanks past me 😅
Thank you! That was really helpful
Best physics videos on TH-cam for a level students
Abu Bardewa Thanks
Physicist pickup lines
"I have here a long rigid beam"
"We could share some moments on it together"
you are actually amazing, i love this so much, too much
What ever happened to romantic pickup lines
"what I like to imagine doing is too add force to it "
Really wish I had discovered you at the start of the year, but nonetheless the videos are amazing for cramming! Thanks a bunch
So clear and straightforward! thank you!
Hearing that first sentence with your eyes closed XD
haha funny
loooool
Hahahaha
got my end of first year physics exam tomorrow your videos are amazing
thank you so much, your videos are very straightforward, and your representation of certain examples with legoes makes things even clearer, awesome videos! thank you
thankyou sir
thanks
Is it possible to get any worked solutions for the Isaac Physics B5 moments questions??
Is there any work done against the forces? Like do they gain kinetic energy whilst rotating because wd=force×d
why is at 1:08 the total moment not 2Fd and rather Fd?? help

Let Fd=1
1/2 + 1/2=1
And 1 is Fd
I made a comment about this but basically:
M = F(d/2) + F(d/2) {initial}
M = F(d/2 + d/2) {factorise}
M = F(d) {add}
M = Fd {final}
What pen do you use?
Pilot V-Sign - it's the best!
Two forces which form a couple can be replaced by a single equivalent forces , That's how ?
Any of the anti parallel forces multiplied the perpendicular distance beteeen them= Tourque of a couple
That's right.
I don't really get it when asks for the driving force of a tyre and then he uses the formula ---> force = torque/radius .... Why didn't he say diameter
r is not radius, it is resistence or force
Where have you been all my life
He lives in England brother
Probably at his house
