## How do the clockwise and the counterclockwise torques compare?

In physics, the **counterclockwise** direction is defined as positive and **clockwise** is negative for rotational variables. **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).

## Why is counterclockwise torque positive?

(Figure) shows **counterclockwise** rotations. The **torque** in (Figure) is **positive** because the direction of the **torque** by the right-hand rule is out of the page along the **positive** z-axis. The disk rotates **counterclockwise** due to the **torque**, in the same direction as a **positive** angular acceleration.

## Is clockwise left or right?

Clockwise is spinning in the direction of an analog clock. It is a way to describe **circular motion**. Left or Right turns are ways of describing a change in approach. Clockwise is constantly turning to the right.

## Why are clockwise moments considered negative?

**Clockwise moments** are **considered negative** when summed with **counterclockwise moments** because they are opposites of each other, but also because **counterclockwise moments** are positive since when acting upon an object, they move the object up on the Y-Axis.

## Is torque positive or negative?

**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**.

## How do you maximize torque?

**Torque** can be increased in two ways: 1) by increasing the moment arm or 2) increasing the perpendicular force applied to the moment arm. The opposite is true for decreasing **torque**. If an object is at rest the **torques** on the object are balanced (they cancel out) and sum of those **torques** is zero.

## Why does torque increase with distance?

At a greater **distance** from the axis the arc is larger, there is more **distance** to cover the same angle. The moment arm affects the force in a **torque** because a larger moment arm, **radius**, or perpendicular **distance** means more **distance** to cover the same angle of rotation.

## What is the rule of balance?

The **rule** for something to be **balanced** is called the principle of moments and is written as follows: The principle of moments. When an object is **balanced** (in equilibrium) the sum of the clockwise moments is equal to the sum of the anticlockwise moments. Force 1 x distance 1 from pivot = Force 2 x distance 2 from pivot.

## 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.

## When an object is experiencing a net torque?

So, a **net torque** will cause an **object** to rotate with an angular acceleration. Because all rotational motions have an axis of rotation, a **torque** must be defined about a rotational axis. A **torque** is a force applied to a point on an **object** about the axis of rotation.

## How do you determine the direction of a couple?

**Determine** the sign of the moment on your own, clockwise is minus, counterclockwise is plus. The vector **direction** of the moment or **couple** is always perpendicular to the plane of the moment or **couple**. Now, when I align my hand along either force and curl towards the other, I always get a negative moment (clockwise).

## What does clockwise mean?

: in the direction in which the hands of a clock rotate as viewed from in front or as if standing on a clock face.

## What does counterclockwise mean in math?

Moving in the opposite direction to the hands on a clock. Also called **Anticlockwise** (British English). Angles from a line are usually measured **counterclockwise**.
