Graphs showing the lean and steer angle response of an otherwise uncontrolled bike, traveling at a forward speed in its stable range (6 m/s), to a steer torque that begins as an impulse and then remains constant. Torque to right causes initial steer to right, lean to left, and eventually a steady-state steer, lean, and turn to left.
Astronaut Sunita "Suni" Williams bungeed to the TVIS treadmill aboard the International Space Station. The Treadmill with Vibration Isolation Stabilization System, commonly abbreviated as TVIS, is a treadmill for use on board the International Space Station and is designed to allow astronauts to run without vibrating delicate microgravity science experiments in adjacent labs.
Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. [1]: 5.14 The name is a misnomer because the cores of the vortices are slightly inboard of the wing tips. [2]: 369 Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.
In the slip, the raised wing — the left one if the airplane is turning to the right — will stall before the lowered one, and the airplane will reduce the bank angle, which prevents the stall. In the skid, the lowered wing will stall before the raised one, and the airplane will tighten the turn, and the stall can develop to a spin.

Counter-rotating propellers generally turn clockwise on the left engine and counterclockwise on the right. The advantage of such designs is that counter-rotating propellers balance the effects of torque and P-factor , meaning that such aircraft do not have a critical engine in the case of engine failure.

An omnidirectional treadmill (ODT) is a mechanical device, similar to a typical treadmill, that allows a person to perform locomotive motion in any direction, allowing for 360 degrees of movement. The ability to move in any direction is how these treadmills differ from their basic counterparts (that permit only unidirectional locomotion ).
