## What is the formula for calculating torque?

The magnitude of torque is equal to the product of the magnitude of the force and the lever arm. The dimensional formula for force is [M¹L¹T⁻²] while for a lever arm it is [L]. Hence, the dimensional formula for torque is [M¹L²T⁻²].

### What is the torque of the force?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.

**What is the formula of differential?**

A differential equation is an equation which contains one or more terms and the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable) dy/dx = f(x)

**How do you calculate torque from force?**

The equation, Force = Torque ÷ [Length × sin (Angle)], converts torque into force. In the equation, Angle is the angle at which the force acts on the lever arm, where 90 degrees signifies direct application.

## Is torque Rxf or FXR?

However, it is clear that the torque is given by the vector equation, torque = r x F. The magnitude of the torque will not change if the directions of either or both of r and F is reversed.

### Why is torque r cross F?

Because torque is a kind of moment. So when u apply a force in outer most layer of a shaft or twist a shaft with one end fixed, the force you given multiplied by the distance from out most layer to centre of the shaft. So torque is equal to force x perpendicular distance.

**Is torque and moment of force same?**

Torque is the measurement of the turning force of a body, while the moment is the measurement of the perpendicular distance from the point of rotation to the force’s line of action.

**What is CF and PI in differential equation?**

C.F. = complementary function & P.I. = Particular Integral or function.

## What is the relation between torque and force?

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.

### Why is torque equal to R cross F?

A particle is located at position r relative to its axis of rotation. When a force F is applied to the particle, only the perpendicular component F⊥ produces a torque. This torque τ = r × F has magnitude τ = |r| |F⊥| = |r| |F| sin θ and is directed outward from the page.

**What is the torque of the force F 2i 3j 4k?**

For this question you just simply need to apply the formula for torque which is r×F where r = (3-0)i +(2-0)j+(3-0)k and F=(2i-3j+4k) , just do the normal cross product calculations which will give you 17i -6j-13k. This is your final torque expression.

**What is r in torque formula?**

The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by ‘r’. Note that this distance, ‘r’, is also a vector, and points from the axis of rotation to the point where the force acts.

## What is the r vector in torque?

The magnitude of the torque depends on the force, the direction of the force, and where the force is applied. The magnitude of the resultant vector is r F sin(θ). r is measured from the axis of rotation to the line of the force, and θ is the angle between r and F.

### How is torque related to moment?

Moment is the perpendicular distance between the point of rotation and the force’s line of action while torque is a measure of the turning force of an object. 3. Torque is used to measure coupling while moment is not.

**How do you find force with torque?**
