Question about computing torque?

In summary, torque is a measure of the rotational force applied to an object and is calculated by multiplying the force by the distance from the point of rotation. The units of torque are typically expressed in newton-meters or foot-pounds. Torque causes an object to rotate around an axis and its direction depends on the direction of the force and the object's moment of inertia. Some real-world applications of torque include cars, bicycles, and industrial machinery. Torque can be increased by increasing the force or distance from the point of rotation, and can be decreased by decreasing the force or distance.

Question about computing torque??

When computing torque of a electic motor I use the formula T=IAB, where as I represents the current, A represents the area, and B represents the magnetic field. My question is, what is the meaning of the product of IA?

IA is the magnetic diapole moment of a current carring loop where I is the current and A is the area of the loop.
 
  • #3


The product of IA in the formula T=IAB represents the strength of the magnetic field created by the current flowing through the area. This is known as the magnetic moment, which is a measure of the strength and orientation of a magnetic dipole. In the context of an electric motor, the magnetic moment created by the current and the area of the motor's coils is responsible for producing the torque that drives the motor's rotation.
 

1. What is torque and how is it calculated?

Torque is a measure of the rotational force applied to an object. It is calculated by multiplying the force applied to an object by its distance from the point of rotation.

2. What are the units of torque?

The units of torque are typically expressed in newton-meters (N·m) or foot-pounds (ft·lb).

3. How does torque affect the motion of an object?

Torque causes an object to rotate around an axis, similar to how a force causes an object to move in a linear direction. The direction of the rotation depends on the direction of the force and the direction of the object's moment of inertia.

4. What are some real-world applications of torque?

Torque is used in many everyday devices and machines, such as cars, bicycles, and door handles. It is also crucial in industrial machinery and robotics.

5. How can torque be increased or decreased?

Torque can be increased by increasing the force applied or by increasing the distance from the point of rotation. It can be decreased by decreasing the force or the distance.
