Understanding the System
In this scenario, we have a uniform circular disc of mass m and radius r, with a point mass m attached at its circumference. The disc is rolling without slipping on a horizontal surface. The key points to consider involve the forces acting on the disc and the acceleration of the point O, which is the center of the disc.
Forces Acting on the Disc
- The weight of the disc and the point mass acts downwards:
- Total weight = m (for disc) + m (for point mass) = 2m
- The normal reaction (N) from the surface acts upwards on the disc.
- The disc also experiences frictional force (f) that prevents slipping.
Acceleration of Point O
- Point O (center of the disc) has a linear acceleration a towards the right.
- The point mass at the circumference has both translational and rotational motion, contributing to its acceleration.
Equations of Motion
- For rolling without slipping, the relationship between linear acceleration (a) and angular acceleration (α) is given by:
a = rα
- The net force acting on the system is given by:
N - 2mg = 0, leading to N = 2mg.
Normal Reaction at this Instant
- The normal reaction N acting on the disc by the horizontal surface is equal to the total weight of the disc and point mass, thus:
N = 2mg.
- This indicates that the disc supports its own weight and the weight of the point mass, maintaining equilibrium in the vertical direction.
Conclusion
In summary, the normal reaction on the disc at this instant is:
N = 2mg.
This analysis reveals how forces are balanced in a rolling system and emphasizes the importance of understanding the dynamics involved.
