Edexcel A Level Maths: 7.6 Pulleys and Connected Particles

Pearson A level maths, applied year 2 textbook (7.6)

In this video I cover:

1. Pulleys
2. Solving problems involving connected particles
3. Particles connected by a light Inextensible string
4. Resolving forces
5. Resultant force exerted on the pulley by the string
6. Finding the acceleration and tension of particles connected by a light Inextensible string
7. Inclined planes and pulleys

Literally watched this 20 minutes before my test. Life saviour, tysm

If still very confused on this chapter i suggest u use exam solutions

asa, 45 min video equals to 5 hours book reading and searching on youtube! Please solve M1 IAL Oct 2023.

Hey sir, I learnt elsewhere that resultant force can be calculated using R = 2Tcosx however this doesn’t work in this instance in the last part of the first question. I beg you to explain please.

Hello, why cant we just use R= 2T Cos Theta for the magnitude of force exerted on pulley by string? As thats the way they did it in the textbook
Thanks

Why dont we take the final part of A ‘s journey acceleration to be 9.8? As when B hits ground, it becomes slack so a travels under acceleration of gravity

[taranparke-antonis]

in Q3 would it work to calculate the change in gravitational potential energy of B which would be equal to the gain in kinetic energy of A and use it to find the velocity of A when B hits the ground as this doesnt seem to be working when I try it. Thanks I've learnt all of mechanics with your videos.
