Torque
What is Torque?
The twisting and turning force that is responsible for the motion of an object is called Torque. Torque is calculated by multiplying the force applied to the arm length. It is calculated in Joule.
What is Torque in a Car?
When an engine exerts itself, torque, which is a twisting force, speaks to the rotational force of the engine and quantifies how much of that twisting force is accessible.
Is Torque a form of Energy?
No, Torque is a form of force not the energy.
What is the difference between Torque and Force?
Torque is defined as the measure of the force that leads to the rotation of an object about its axis. While, Force is the reason that causes an object to accelerate in linear kinematics.
What is the Difference Between Torque and Moment?
Moment is the measurement of the angle between the rotational axis and the force’s line of action, whereas torque is the force that turns a body.
How can we Increase or Decrease Torque?
Both the moment arm and the perpendicular force supplied to the moment arm can be raised to increase torque. When torque decreases, the opposite is true. When an object is at rest, its torques are balanced (they cancel out), and their sum is zero.
Why is it Difficult to Open the door by Pushing it or Pulling it at the Hinges?
When the force is applied at hinges, the perpendicular distance between the line of action to the axis of rotation that’s
r = 0
τ = rFsin(θ)
τ = 0
That’s why one cannot open the door by pushing or pulling it at the hinges.
When Torque is Zero?
If the rotating force is applied at the point of rotation of the arm then the torque produced is zero.
Torque
Torque is the effect of force when it is applied to an object containing a pivot point or the axis of rotation (the point at which an object rotates), which results in the form of rotational motion of the object. The Force causes objects to accelerate in the linear direction in which the force is applied, but in the case of torque, it causes objects to accelerate in the angular direction with respect to the axis of rotation. Torque is also called the “moment of force,” as it depends on the magnitude of the force as well as the moment of the arm, i.e., the perpendicular distance between the line of action force and the axis of rotation. Torque is as fundamental to rotational motion as force is to a straight-line motion. In this article, we will learn about torque and how torque has a tendency to cause rotation, also how to solve numerical problems based on Torque as well.
