**What do mean by torque?** Torque is **a twisting force that speaks to the engine’s rotational force and measures how much of that twisting force is available when an engine exerts itself**. Torque is present in everyday happenings, such as operating a doorknob, opening a soda bottle, using a wrench, or pedaling a bicycle.

**What is torque and its unit?** Solution : Torque is defined as **the moment of the external applied force about a point or axis of rotation**. Its unit is Nm.

**What is the value of torque in physics?** Torque is defined as **Γ=r×F=rFsin(θ)**. In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.

**What is the formula for torque?** Lesson Summary. Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically, torque can be written as **T = F * r * sin(theta)**, and it has units of Newton-meters.

## What do mean by torque? – Additional Questions

### What is a torque in motor?

Torque: The torque output of a motor is **the amount of rotational force that the motor develops**. The torque of a small electric motor is commonly measured in either inch pounds (in-lbs), Newton meters (N-m) or other directly converted units of measure.

### What is torque balance?

**When the torques on either side of a fulcrum are equal**, they are called balanced torques. A common example of balanced torques is two children on a see-saw. If the fulcrum is in the center of the see-saw, the two children must have equal mass for it to be balanced.

### Is torque a force?

What is 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.

### What is positive torque?

The rotation of a clock’s hands is the reference for defining rotational direction. 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).

### What happens when torque is zero?

Because there is no net torque acting on an object in equilibrium, an object at rest will stay at rest, and an object in constant angular motion will stay in angular motion.

### How do you increase torque?

An effective modification that will increase torque significantly is to **install a turbo or supercharger**. Forced induction forces air into your engine, increasing the power the engine provides. Depending on the torque curve you prefer, a turbocharger will need time to spool before it provides torque benefits.

### What does torque depend on?

The magnitude of torque of a rigid body depends on three quantities: **the force applied, the lever arm vector connecting the point about which the torque is being measured to the point of force application, and the angle between the force and lever arm vectors**.

### Is torque always positive?

Oh, **torque can be positive or negative**. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise. If you switched these, it wouldn’t really matter too much.

### Can u have negative torque?

Negative Torque is said to occur when conditions are such that air loading on a propeller causes it to drive the engine to which it is attached vice the normal condition in which the engine drives the propeller.

### Why does torque have direction?

The direction of the force is important because **the resulting motion of the object is in the same direction as the force**. The product of the force and the perpendicular distance to the center of gravity for an unconfined object, or to the pivot for a confined object, is^M called the torque or the moment.

### What is meant by negative torque?

The negative driving torque is defined as **torque applied to load in the reverse direction of the motor rotation**. When the servomotor driver controls the motor to drive its load with negative driving torque, the effects of the negative driving torque may damage the servomotor driver.

### Which torque has positive nature?

The fact that the optical torque is **positive on the blue side** and negative on the red side of a LP resonance connects the spectroscopic properties of the NP cluster to its dynamical properties, and further clarifies the regions of negative torque observed in the torque phase diagram (Fig. 3).

### Can rpm be negative?

Re: negative RPM

**Negative rpm is acceptable in FLUENT**.

### Does length affect torque?

EXAMPLE 1: The longer the lever arm, then for the same force, the greater the torque. EXAMPLE 2: **The greater the applied force, then for the same lever arm length, the greater the torque**. EXAMPLE 3: The larger the gear, then for the same force, the greater the torque.

### What is the difference between torque and force?

Torque is when a force is applied to a particular object that results in the object moving by rotating around an axis. A force is some type of action that results in a body changing in motion or altering the path of motion.

### Who discovered torque?

The concept of torque, also called moment of a force, as you’ve pointed out correctly, originated with the studies of Archimedes on levers. The term torque was apparently introduced into English scientific literature by **James Thomson**, the brother of Lord Kelvin, in 1884, as suggested here.

### In what direction does torque reverse?

When motor exerts torque in clockwise direction it rotates in the clockwise direction and when the motor exerts torque in **anti clockwise direction**, the motor rotates in the anti clockwise direction. Thus, the direction of the DC motor can be reversed by reversing the direction of the torque.
