Why do airplanes make skid markes when they land??
In a wheeled vehicle, there will be a fixed angular velocity for the wheel for each speeds of the vehicle. A skid occurs when the instantaneous angular velocity of the wheel does not match with the required value. (i.e. excess torque causing wheelspin or incorrect braking causing wheel locks) When the aircraft touches down, the wheels are not turning. The tires are the points of contacts during this collision and the resultant forces causes the wheels to spin. Inertia of the wheels resists the angular acceleration and so the mismatch of angular velocities occur. Tires burns, marks…
