The torque caused by the two opposing forces F < sub > g </ sub > and-F < sub > g </ sub > causes a change in the angular momentum L in the direction of that torque ( since torque is the time derivative of angular momentum ).

Torque-induced precession ( gyroscopic precession ) is the phenomenon in which the axis of a spinning object ( e. g., a part of a gyroscope ) " wobbles " when a torque is applied to it, which causes a distribution of force around the acted axis.

The torque caused by the two opposing forces F < sub > g </ sub > and-F < sub > g </ sub > causes a change in the angular momentum L in the direction of that torque.

The torque caused by the two opposing forces F < sub > g </ sub > and − F < sub > g </ sub > causes a change in the angular momentum L in the direction of that torque.

The gravitational torque between the Moon and the tidal bulge of the Earth causes the Moon to be promoted in its orbit, and the Earth to be decelerated in its rotation.

Rotation of the servo in the other direction causes torque to be applied to a linkage and cam which causes friction with the braking material.

As with any twin cylinder engine, they have an imbalanced firing action which causes vibration and inline-twins also suffer further from torsional torque reactions and vibration.

In a motor, the armature current causes the fixed magnetic field to exert a rotational force, or a torque, on the winding to make it turn.

* A torque, the force that causes it, and the position of the point of application of the force

The resulting torque causes the hull to heel until the buoyancy of the hull provides sufficient torque to balance the heeling force.

But because of the Earth's equatorial bulge, an orbit inclined at a slight angle is subject to a torque which causes precession ; it turns out that an angle of about 8 degrees from the pole produces the desired precession in a 100 minute orbit.

This action causes a substantial increase in the mass of fluid being directed to the turbine, producing an increase in output torque.

An example of a ratcheting CVT is one prototyped as a bicycle transmission protected under in which strong pedalling torque causes this mechanism to react against the spring, moving the ring gear / chainwheel assembly toward a concentric, lower gear position.

In many applications torque gains are even greater as increased fuel is burnt at a lower rpm range and is what causes the significant improvement in acceleration.

The polar axis moves due to various causes, some predictable ( the Moon exerts a torque on Earth's tidal bulge ) and some variable ( rocks are rebounding from the last ice age, weather ).

If the train starts to climb an incline, the speed reduces because drag is greater than torque and the reduction in speed causes the back-EMF to fall and thus the effective voltage to rise-until the current through the motor produces enough torque to match the new drag.

Once released, gravitational force ( called torque ) brings the Weeble back into an upright position, though inertia causes the toy to wobble briefly before coming to a standstill.

At high speeds the ailerons could apply more torque than the Spitfire's thin wings could handle, and the entire wing would twist in the opposite direction.

Combined over the entire wheel, there is a torque around the gimbal axis when some spinning is added to rotation around a vertical axis.

Input torque is applied to the ring gear ( blue ), which turns the entire carrier ( blue ).

The changeover process occurred at 4500 rpm,, was smooth, and provided linear acceleration and a wide torque curve throughout the entire rev range.

Since the wind pulls each blade around on both the windward and leeward sides of the turbine, this feature spreads the torque evenly over the entire revolution, thus preventing destructive pulsations.

The entire craft had a low rotational inertia, and torque from the spinning rotor blades made the body spin, unless counteracted by yaw thrust in the opposite direction.

BMW, working with Robert Bosch GmbH and Continental Automotive Systems, developed a system to reduce engine torque to prevent loss of control and applied it to the entire BMW model line for 1992.

In 2003 the 2. 2L OHV L4 was dropped from the entire Cavalier line, and the Cavalier Z24 was dropped and replaced by the LS Sport line, which featured the new Ecotec L61 motors ( and torque ).

This effect optimizes volumetric efficiency over a given rpm range to provide maximum torque over the entire rpm range.

The ECA1 motor is assisted in various circumstances by a 10 kW permanent magnet DC electric motor adding and torque throughout the entire rpm range.

* Efficient engine torque limitation is achieved over the entire load and engine speed range

The friction across the entire surface area of the interface provides a large amount of torque transmission, so that splines or keys are not required.

In the 1950s and 1960s, Cotal used this same technology to provide an electric clutch ( with full manual changes through a normal gearbox, but no clutch pedal ) for small Renaults like the Dauphine and Caravelle, but it was relatively unsuccessful-it needed to transmit the entire engine torque through the clutch, requiring a relatively large and powerful clutch that tended to give trouble with the sliprings.

YPVS Yamaha engines, Yamaha Power Valve System: Yamaha engineers realized that by altering the height of the exhaust port they could effectively change the engine power delivery thereby having optimal power and torque across the entire rev range, so it was that the YPVS was born.

Thus if the gyro and platform-controller combination maintains the platform with zero angular deviation about the **yf axis, the system can be rotated with an angular velocity Af if a torque is supplied to the gyro output axis Aj.

Angular momentum is conserved in a system where there is no net external torque, and its conservation helps explain many diverse phenomena.

Relationship between force ( F ), torque ( τ ), momentum ( p ), and angular momentum ( L ) vectors in a rotating system

The law of conservation of angular momentum states that when no external torque acts on an object or a closed system of objects, no change of angular momentum can occur.

) So requiring the system to be " closed " here is mathematically equivalent to zero external torque acting on the system:

where is any torque applied to the system of particles.

The conservation of angular momentum in Earth – Moon system results in the transfer of angular momentum from Earth to Moon ( due to tidal torque the Moon exerts on the Earth ).

For example, in an automobile with cruise control the vehicle's speed is continuously monitored and fed back to the system, which adjusts the motor's torque accordingly.

Its name comes from the information path in the system: process inputs ( e. g., voltage applied to an electric motor ) have an effect on the process outputs ( e. g., speed or torque of the motor ), which is measured with sensors and processed by the controller ; the result ( the control signal ) is " fed back " as input to the process, closing the loop.

For example, the earth is subject to local torque induced precession due to the gravity of the sun and moon acting upon the earth ’ s axis, but at the same time the solar system is moving around the galactic center.

The response of a rotating system to an applied torque.

By Newton's first law, this situation implies that the net force and net torque ( also known as moment of force ) on every part of the system is zero.

Relationship between force F, torque τ, linear momentum p, and angular momentum L in a system which has rotation constrained in one plane only ( forces and moments due to gravity and friction not considered ).

When the net force on the system is zero, the torque measured from any point in space is the same.

The system is designed to minimize Lorentz torque on the rotor.

In a live-axle suspension system, the axles serve to transmit driving torque to the wheel, as well as to maintain the position of the wheels relative to each other and to the vehicle body.

In other types of suspension systems, the axles serve only to transmit driving torque to the wheels ; The position and angle of the wheel hubs is a function of the suspension system.

In 1995, with a new version of the Scorpio, it was upgraded with a wider torque spread and higher power-to, from a variable intake system and reprofiled cams.

The SuperVeloce's V12 produces at 8000 rpm and of torque at 6500 rpm, thanks to revised valve timing and upgraded intake system.

The hub axle of a hub gear ( unlike that of a derailleur system ) will carry torque in all gears except direct drive, and so must be securely braced against rotation.

Many newer vehicles feature traction control, which partially mitigates the poor traction characteristics of an open differential by using the anti-lock braking system to limit or stop the slippage of the low traction wheel, increasing the torque that can be applied to both wheels.

The slower moving wheel received more driving torque than the faster one, so the system had limited-slip characteristics.
