1 Answer1. Show activity on this post. It is the friction between the pulley and rope due to which the factor T 1 R − T 2 R appears in the equation. Due to friction,the tensions in the ropes on either ends cannot be same [ The relation is actually T 1 = T 2 e μ θ; μ → coefficient of friction, θ → angle of wrap of rope around pulley] The friction prevents slipping between rope and pulley and actually causes pulley to turn with the rope.
