Angle of REPOSE or Angle of SLIDING | explained in HINDI

In this Physics video lecture in Hindi for class 11 we explained angle of repose or angle of sliding. During the derivation of the formula we found that the tangent of angle of repose is equal to the coefficient of static friction between the surfaces. We considered an example of two wooden blocks. As the coefficient of friction increases the angle of repose increases. Angle of repose for two surfaces (bodies) is the angle for which one body just slides over another one. For this experiment we placed one wooden bar over another and raised the bottom bar forming an inclned plane. At some point the top bar starts sliding. In this situation the angle of inclination of the lower bar with the horizontal is called the angle of repose or sliding. ★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel :    / @edupoint.physics   EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.
