What is torque 12th?
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.
How is torque calculated in physics?
A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.
How do you interpret 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 torque 11th?
What is torque Shaalaa?
The turning effect produced by a force on a rigid body about a point, pivot or fulcrum is called the moment of force or torque. It is measured by the product of force and the perpendicular distance of the pivot from the line of action of force.
What is torque and speed?
Torque relates to the rotational force of an electric motor while speed refers to the rate that the motor can rotate. This means that torque is associated with rotational force while speed relates to the rate of rotation which can be calculated by examining the RPMs, or revolutions per minute.
What does higher torque mean?
Engine power and torque are both indicators that depend on the engine speed. A high torque enables efficient and energy-saving driving. A high engine power enables a car to accelerate quickly and reach a high top speed.
How do you explain torque to a child?
The force applied to a lever, multiplied by its distance from the lever’s fulcrum, is the torque. For example, a force of three newtons applied two metres from the fulcrum exerts the same torque as one newton applied six metres from the fulcrum.
What is torque simple?
1 : a force that produces or tends to produce rotation or torsion an automobile engine delivers torque to the drive shaft also : a measure of the effectiveness of such a force that consists of the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation.
What is torque write its unit?
The turning effect of a force about the axis of rotation is called moment of force or torque due to the force. SI unit of torque is Nm.
What is torque vs power?
Torque refers to the capacity to do work, while power is the rate of completing work in a given amount of time. The primary use of torque is to make the car accelerate in the initial stages of movement, while the horsepower determines the rate of the acceleration of the vehicle.
How is RPM and torque related?
Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.
Why is torque maximum at 90 degrees?
“The torque produced by the elbow flexors is greatest at 90 degrees flexion because the force of flexion is farthest away from the axis (greatest perpendicular distance) and the actin and myosin overlap are optimum for force production.”
What is the torque?
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 torque of linear force?
Hence, torque can be defined as the rotational equivalent of linear force. The point where the object rotates is called the axis of rotation. In physics, torque is simply the tendency of a force to turn or twist.
What determines the amount of torque produced?
Now, from the above observation, we conclude that torque produced depends on the magnitude of the force and the perpendicular distance between the point about which torque is calculated and the point of application of force. So, mathematically torque is represented as: The unit of torque is Newton–meter (N-m).
What is the SI unit for torque?
The SI unit for torque is the Newton-meter. In imperial units, the Foot-pound is often used. This is confusing because colloquially the pound is sometimes used as a unit of mass and sometimes force. What is meant here is pound-force, the force due to earth gravity on a one-pound object.
