This Pure Rolling Problem Confuses Everyone 🤯 | Pathfinder Rotational Mechanics CYU-2

Pure rolling sounds easy… until two strings get involved 👀 In this video, we solve CYU-2 from Pathfinder Rotational Mechanics, where a cylinder is wrapped with two strings and released. The key challenge is to correctly apply the pure rolling condition and find the velocity of the centre of mass without falling into common conceptual traps. 🔍 What this video covers: • Identifying the correct point of rolling • Why blindly using v = Rw can be dangerous • How constraint relations from strings affect motion • Step-by-step reasoning (not shortcut-based) • The exact logic needed for JEE Advanced–level problems 💡 This is one of those problems where concept is greater than formula, and once it clicks, a whole class of rotational mechanics questions becomes easy. 📌 Highly recommended for students struggling with pure rolling + strings + constraints.
