Why is Torque Important?
Torque is an important concept of physics that helps us understand how things happen around us. With the help of torque, it can be determined what the direction and magnitude of a rotational force applied on an object is, allowing you to assess the results it may generate. Generally, torque can help you determine whether the force applied will result in counterclockwise or clockwise motion. Not only that, it can also help you predict the angular acceleration from which the object is being rotated. Since torque can be large or small, it is measured in different units, and can be easily converted in all those units with the help of an online torque converter.
Torque Units of Measurement
Torque can be measured in a number of different units, such as:
- Kilogram centimeter
- Newton centimeter
- Dyne centimeter
- Gram centimeter
- Kilogram meter
- Pound inch
- Pound foot
- Ounce foot
- Ounce inch
You can easily do online torque conversion with the help of a torque converter. It is extremely easy to use and provides accurate answers for conversion in all the above units. All you need to do is input the value of torque, select the original unit, select the unit you want to convert into, and you will get the answer.
Real-life Applications of Torque
Whenever there is a force causing a turning or rotating movement, torque is bound to be produced. In real life, you may not realize it, but there are many applications of torque that are happening all around us – we just don’t realize it. To give you an idea, here are some common and complex applications of torque that you may find interesting:
If you have ever used a wrench, you would get the idea of how torque is applied if you have understood how it works. When you use a wrench to tighten or loosen a nut around a bolt, you apply a pulling force around the rotation axis of the nut, allowing the torque to kick in and rotate. Since several forces are acting simultaneously on the lever arm or wrench, you have to take a sum of all those forces and multiply it with the length from the force application point to the pivot point to get the amount of torque. If you want to increase the torque for turning the nut around the bolt, you will have to increase the distance of the force application point to the pivot point or increase the amount of force being applied.
Another common example of torque in everyday life is hinged doors. When you open a door, the torque applied in the situation allows it to move around the rotational axis. Here, the pivot point is the hinges, and if you apply force near the hinges, you are likely to face difficulty in opening it. On the other hand, when the force is applied at the furthest end from the hinges or the door’s knob, you will see that it is much easier and you will have to apply a lot less force in opening it.
Another classic example of torque is the seesaw, and most of us have used it to play with our friends when we were younger. The mechanism of seesaw is quite simple: one person sit on its one end and another person sits on its other end. Since there is a difference in weight of both persons, the heavier person lifts the lighter person. However, when the heavier person comes close to the pivot point, the length decreases, resulting in less amount of torque applied and allowing the lighter person to lift the heavier person. This happens because the difference in distance or length from the pivot point cause the value of torque to change.
Have you ever noticed that the steering wheel of a car is smaller than that of an 18-wheeler, though they do the exact same thing? This is because maneuvering or turning an 18-wheeler requires a lot more force than doing so for a car. By increasing the radius of the steering wheel from the pivot point, the amount of force required for applying the torque reduces, making it easy for the driver of a truck to turn the steering wheel.
Why Use an Online Torque Converter?
Torque is used in many aspects of our lives, and plays an important role in determining how much force and in which direction is required for carrying out a certain task. Whether you are using a wrench, riding a bicycle, driving a car or any other thing, there are many ways torque is making things happen around you. If you want to convert torque into different units, you can easily do so by using an online torque converter. It provides accurate values and a wide range of online torque conversion options to help you with the calculation of torque.
You may have heard the term torque in commercials and advertisements of big truck manufacturing companies, boasting about the impressive torque and horsepower of their engines. They tend to wow their customers with big numbers, luring them into believing that the bigger always the better. However, in order to determine what those numbers mean and the effect they will have on the speed and other aspects of your car, you need to understand the concept on the basic level.
Torque is not only used in cars – it is a physics concept that is applied in a myriad of applications, from something as simple as seesaws to complex machinery and much more. The quantity is measured in several units, belonging to different measurements systems, like SI, CGS, etc., hence a torque converter can greatly help in understanding the concept. Online torque conversion allows you to see how the values of torque vary in different measurement systems, and get accurate results.
Also known as moment of force or simply moment, torque refers to the rotational force to rotate an object about a pivot, fulcrum, axis. The concept of torque is very similar to force – meaning that force is all about pushing and pulling an object, while torque is something that causes an object to twist or rotate. In layman terms, when you see a flywheel or bolt twist, the force that is expended in turning that object is torque in action.
Torque is dependent on several things, such as:
- The force magnitude
- The distance between the point of force application and the rotation axis
- The force orientation in relation to the displacement from the point of force application to the axis
The magnitude of the torque is measured with the help of the formula, τ = N-m. Here, N is newton, a unit of force, and m is meter, unit of distance.
Pivot refers to the rotation point in any lever system, or you can say that it is the center point of the entire rotational system which is twisting or moving due to torque. Take the example of a bicycle: the center point or hole in the center of a bike is the pivot from where the gears rotate.
Momentum arm is also referred to as lever arm, and is defined as the perpendicular distance from the rotational center point of an object. Torque is always defined from a point of rotation or pivot point, which means that torque increases with the increase in angular acceleration.
The resting or supporting point on which a lever pivots is known as fulcrum. In case of a bicycle, you can easily see the resting place of the gears and lever that provide assistance to the bike chain to pivot or rotate.
When a number of forces act on varying points, it causes the lever to make a turning movement, or in other words, applying torque on the object. Such forces are known as non-concurrent forces.
When different forces causing the motion pass through a common point, they are represented by one net force, known as a concurrent force.
It is the line along which the resultant forces are likely to act is the line-of-action. In the bicycle example, the focal point of contact for all forces is the teeth of the gears.
An object in rotational equilibrium means that it is neither moving or rotating, and its angular and linear accelerations are zero.
When two equal forces are acting on an object in opposite directions and in different points to create a turning effect, such forces are known as a couple.
