## What is a positive torque?

Counterclockwise is the positive rotation direction and clockwise is the negative direction.

For example, a torque that rotates an object counterclockwise is a positive torque (see figure 6 below).

…

An applied force that causes a positive counterclockwise torque..

## What is the formula to calculate torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.

## Can you have negative torque?

Torque is a vector quantity that has direction as well as magnitude. Turning the handle of a screwdriver clockwise and then counterclockwise will advance the screw first inward and then outward. By convention, counterclockwise torques are positive and clockwise torques are negative.

## Does higher torque mean faster acceleration?

A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … Higher torque doesn’t mean one vehicle will necessarily be faster than another, though. For example, a Ford F-250 makes 925 lb-ft of torque, while a Honda S2000 has just 162 lb-ft.

## How many HP is RPM?

Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

## What is full load torque?

The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. In imperial units the Full-load Torque can be expressed as. T = 5252 Php / nr (1)

## What gives rise to torque?

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. … The direction of the torque vector depends on the direction of the force on the axis.

## What is initial torque?

Initial torques are indicated in Newton metre (Nm). 1 Nm means: on a hand gear of 1m works a force of 1 Nm. The value of the initial torque describes the maximum force that should be used for tightening the fixing elements against the sensor housing.

## How much torque is 1 horsepower?

The definition of 1 Horsepower is displacing 1 lb. 33,000 ft. in one minute or 33,000 lb-ft / minute.

## How many rpm is 1 HP?

When the 1HP pump is operating in the optimal range (approx. 2700 rpm) the 3600 RPM motor is still be producing 1.5 ft/lbs of torque, while the 1800 RPM motor’s output will be somewhere between 1.5 and 3 ft/lbs.

## What is low starting torque?

So starting torque is low in induction motors. To get maximum starting torque, resistance is added to the rotor while starting slip ring motors, which is reduced gradually as motor picks up the speed. … So starting torque is low in induction motors.

## What is pull out torque?

Pull-out torque is the maximum torque that can be delivered without losing steps. It reaches its maximum at the lowest frequency or speed, and decreases as frequency increases. … Pull-in torque is the maximum torque at which a motor can start rotating at a given frequency.

## Does torque have direction?

Right Hand Rule for Torque Torque is inherently a vector quantity. Part of the torque calculation is the determination of direction. The direction is perpendicular to both the radius from the axis and to the force. It is conventional to choose it in the right hand rule direction along the axis of rotation.
