The force velocity relationship is the observation that muscle force and contraction velocity are inversely related. A key concept for athletic performance!. System Dynamics. The model identifies the wheel speed and vehicle speed as state The dynamic equation for the angular motion of the wheel is x. [. ]/ ωw torque, tire tractive force, wheel friction force, normal reaction force from the ground.
You can resolve the velocity of any point on the wheel surface into horizontal and vertical components. The contact point is stationary. I arranged that by adding just the right amount to the horizontal velocity. For any given piece of the wheel these equations are instantaneous: This means the material in the wheel is accelerating, which means there must be a force towards the centre centripetal forcewhich means there must be spokes or something connecting it to the axle or the wheel must be sufficiently strong.
For the top most point at a particular instant, the linear velocity will be horizontal forward. Slipping means all the points of the wheel will be moving with same velocity. So, there is no rotatory motion and hence no additional linear component of velocity.
Hence the above equation is valid only when the wheel is rolling without slipping. Slipping or skidding of wheels of a vehicle occurs when the brakes are fully applied and still the vehicle is moving but the wheels are not rotating.
Also, this condition is valid for a particular point at a particular instant only.
