The weight transfer under acceleration has the opposite effect and either may dominate, depending on the conditions. Inducing oversteer by applying power in a front wheel drive car is possible via proper use of "left-foot braking”, and using low gears down steep hills may cause some oversteer.
Early hydraulic dynamometer, with dead-weight torque measurement. An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
A Fast Falling Weight Deflectometer (FFWD) is a FWD with pneumatic or electric actuators rather than hydraulic, making the mechanics several times faster. A Heavy Weight Deflectometer (HWD) is a falling weight deflectometer that has higher loads (typically 300 kN to 600 kN), used primarily for testing airport pavements.
Most 3-wheel velomobiles drive (power) the single rear wheel, and a four-wheel velomobile with two driven wheels may have better drive traction. One reason is that many tricycles put about 1/3 of total weight on the drive wheel, while many quads put about 1/2 weight on the two drive wheels.
Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st
Huygens' maintaining power in use. The weight drive used by Christiaan Huygens in his early clocks acts as a maintaining power. In this layout, the weight which drives the clock is carried on a pulley and the cord (or chain) supporting the weight is wrapped around the main driving wheel on one side and the rewinding wheel on the other.
In a front-engine rear-drive vehicle, dependent rear suspension is either "live-axle" or deDion axle, depending on whether or not differential is carried on the axle. Live-axle is simpler, but unsprung weight contributes to wheel bounce.
In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 r/min (about 5–7 m/s (18–25 km/h; 11–16 mph) with recent high sensitivity sensors) or higher, 300 r/min (about 25–27 m/s (90–97 km/h; 56–60 mph) with typical low sensitivity sensors), and forces of unbalance are ...
