If a wheel always stops in the same position when it is free to turn about its axis, it suggests that the wheel is in a state of stable equilibrium. This indicates that the wheel's center of mass is directly above its point of contact with the surface it rests on, creating a balanced system. The wheel's moment of inertia may also play a role in determining its behavior when free to turn about its axis.
If a wheel always stops in the same position when free to turn about its axis, it suggests that the wheel has some form of asymmetry or bias, such as a heavy spot or uneven distribution of mass. This imbalance causes it to settle in a specific orientation due to gravitational forces acting on its center of mass. This phenomenon indicates that the wheel is not perfectly balanced, which affects its rotational behavior.
In such graphs the x-axis is usually (but not always) the time axis. The x-intercept represents the time(s) at which your position is at the starting point - either for the first time or later.
Yes, it is true that a wheel is a circular object that rotates on an axis.
False
Generally a grinding sound can be heard from the offending wheel at first. If a wheel bearing is suspect, jack one side of the car up at a time and grab the wheel at the 12 and 6 o'clock position and see if the wheel has excessive play on the horizontal axis. If there is play, then a wheel bearing failure is likely.
The Earth's axis is an imaginary line passing through the north and south poles. It is like an axle is to a wheel. The Earth rotates on this axis like the wheel rotates on its axle.
A position-time graph, is one in which position is plotted on the y-axis and the time is on the x-axis. A position-time graph is similar to a distance-time graph, but direction of motion in the y-axis.
The is the measure of the steering axis relative to vertical. It affects how the car tracks and the tendency of the wheels to return to the straight ahead position when the steering wheel is released.
Parallelism of AxisThe earth is constantly rotating as it revolves about the sun. It rotates on an imaginary axis. The earth's axis always points in one direction. Thus as the earth revolves about the sun, the position of the axis at any one time is always parallel to the position it occupied at any previous time. This phenomenon is called parallelism of axis.It always points to the pole star.

The earth is always tilted on its axis. It is about 23.5o
