Ratio of Tension in Flat Belt Drive_Full Concept

Whenever belt drives or band brakes are designed, it is necessary to determine the frictional forces developed between the belt and its contacting surface. In this video we will analyze the frictional forces acting on a flat belt, although the analysis of other types of belts, such as the V-belt, is based on similar principles.

For anyone wondering how angle is dx/2 on other side.
Split angle dx in two parts dx/2 and dx/2 .
First find the unknown angle in the 📐 with force F and resultant R which would be (90-dx/2)
Then the force line which 180degree with a angle tension unknown lets call it angle(y). Force F and Tension T will form a 90degree angle as 📐
Y= 180-90-(90-dx/2)
Y=180-90-90+dx/2
Hence , angle(Y)=dx/2

awesome ❤!!
sir can u please tell me why dont we take friction in tangential direction ?
thank you sir
