When a truck’s tires spin in loose gravel, they struggle to gain traction, often leaving the vehicle stuck.

The friction between the tires and the log provides a stable surface for the tires to grip, allowing the truck to push forward instead of continuing to slip. This method functions similarly to the use of a wedge in physics, where increased contact surface and applied force help move objects more ef

The Vortex Ring State (VRS) is a dangerous condition for helicopters, occurring when the rotor descends into its own downwash, creating a turbulent vortex that causes a sudden loss of lift and control. This usually happens during vertical descents or hovering, especially at high descent rates and low airspeeds. Attempts to increase power can worsen the vortex, accelerating descent unexpectedly. To recover, pilots use forward cyclic control to move the rotor out of its downwash and reduce collect
