does anybody know the rules to find minimum velocy in a rod laying against the wall with specific angle??
The minimum velocity needed for a rod to stay against a wall depends on several factors such as the length and weight of the rod, the angle at which it is leaning against the wall, and the coefficient of friction between the rod and the wall. Therefore, there is no single minimum velocity that can be determined.
The longer the rod, the higher the minimum velocity needed for it to stay against the wall. This is because a longer rod has more surface area in contact with the wall, resulting in a larger frictional force that needs to be overcome.
The angle at which the rod is leaning against the wall affects the minimum velocity needed for it to stay in place. A rod that is perpendicular to the wall will require a higher minimum velocity compared to a rod that is leaning at a smaller angle. This is because a perpendicular rod has a larger component of its weight acting parallel to the wall, increasing the frictional force.
Yes, the weight of the rod plays a significant role in determining the minimum velocity needed for it to stay against the wall. A heavier rod will require a higher minimum velocity to overcome its weight and the frictional force between the rod and the wall.
The coefficient of friction is a measure of the amount of friction between two surfaces. A higher coefficient of friction means that the rod will require a higher minimum velocity to overcome the frictional force and remain against the wall. This is because a higher coefficient of friction indicates a stronger grip between the rod and the wall.
