How to CALCULATE the magnitude of force exerted on a Pulley - TWO METHODS!!! A level Mechanics Prep

Hi! I am @alevelmathstutoruk and I produce videos covering the A-level Maths syllabus in the UK. I am a first class BSc Mathematics graduate from a Russell Group UK university and I am currently working as an online maths tutor.

In today's video I demonstrate two methods in which we can use to calculate the force exerted onto a pulley by a light in-extensible string connecting two particles - one being on a rough inclined surface, and one hanging in the air. I provide a full solution to this calculation using both approaches.
