The plane which is defined by the head-to-foot and anterior-to-posterior directions in the human body. A stack of images acquired in the sagittal plane separates images by their left-to-right locations. The mid-line sagittal plane bisects the left and right half of the human body.
Under heavy braking, the rear tires lock up and the axle begins to bounce; the amplitude of the bounce becomes so severe that the tires finally develop enough traction (when slamming hard against the pavement) to rip the whole axle assembly free of the vehicle.
A classic example of an extreme static imbalance is a bucket swung on a rope. Even if you stop swinging the bucket its stored energy will drag your hand in a circle until it stops. Now think of your carâs suspension as your hand and youâll see why that energy causes the car to shake. An equal amount of weight (a counterweight) applied at the inverse angle of the imbalance will statically balance a wheel.
