How is torque calculated Khan Academy?

The way you find the torque from a given force is you take r, the distance from the axis to where that force is applied and you multiply by the amount of force, as long as it’s that amount of force that runs perpendicular to this lever arm or this r direction. Be careful that torque is a vector.

How do you solve torque problems in physics?

Finding Net Torque Take the cross product of r → and F → r → and F → to determine if the torque is positive or negative about the pivot point or axis. Evaluate the magnitude of the torque using r ⊥ F r ⊥ F . Assign the appropriate sign, positive or negative, to the magnitude. Sum the torques to find the net torque.

How do you explain 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 right hand rule for torque?

The direction of the torque can be found by the right-hand rule for cross products: put your fingers in the direction of the first vector ( ) and your palm facing in the direction of the second vector ( ); your thumb will point in the direction of the cross product ( ).

How do you calculate rpm torque?

  1. Torque ( = 63,025 x Power (HP) / Speed (RPM)
  2. Power (HP) = Torque ( x Speed (RPM) / 63,025.
  3. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
  4. Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

What is torque simple words?

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 the theory of torque?

Torque (also known as moment, or moment of force) is the tendency of a force to cause or change the rotational motion of a body. It is a twist or turning force on an object. Torque is calculated by multiplying force and distance. It is a vector quantity, meaning it has both a direction and a magnitude.
