The locus of a point on the circumference of a circle as it rolls without slipping on a straight line is called a cycloid. In this case, the circle has a diameter of 46mm and makes 1½ revolutions.
To understand how the locus is formed, imagine a point P on the circumference of the rolling circle. As the circle rolls without slipping, point P traces a path on the ground.
To determine the shape of this path, we can divide the rolling motion into two parts: the horizontal and vertical components.
1. Horizontal Component:
During each revolution, the point P moves a distance equal to the circumference of the circle, which is π times the diameter. In this case, the diameter is 46mm, so the circumference is 46π mm.
Since the circle makes 1½ revolutions, the total horizontal distance covered by point P is 1½ times the circumference of the circle, which is 1½ * 46π mm.
2. Vertical Component:
The vertical distance covered by point P is equal to the diameter of the circle, which is 46mm.
Combining the horizontal and vertical components, we can plot the locus of point P. Each point on the locus represents the position of point P as the circle rolls.
To draw the locus, we can start by marking the initial position of point P at the starting point of the rolling circle. From there, we can calculate the coordinates of point P at regular intervals, corresponding to the distances covered by the circle.
For example, if we divide the total horizontal distance covered by point P into 10 equal intervals, we can calculate the x-coordinate for each interval by dividing the total distance by 10.
Similarly, since the vertical distance remains constant, the y-coordinate of point P remains the same throughout.
By plotting these coordinates, we can trace the shape of the locus of point P as a cycloid.
