Torque

Torque is also known as the force moment or moment can be defined as the force’s tendency to change or cause rotational motion of a particular body. It is specifically a turning or twisting force of a particular object. Torque is specifically calculated through the multiplication of distance and force. It is essentially a vector quantity. This means that the quantity has both magnitude and direction. Here it can be seen that the moment of inertia’s angular velocity is varying or both are varying. 

Torque physics 

Torque physics is a rather important concept in the subject of Physics. It is essentially a measure that is used for calculating the force that specifically causes the rotation of an object around an axis. In this regard the concept of force is important. Force is described as the cause due to which an object starts accelerating in linear kinematics. Torque has a similar definition and is the main reason behind angular acceleration. Thus in simple terms torque is defined as a linear force’s rotational equivalent. The particular point at which the axis rotates is known as the axis of rotation. In physics, torque is the force’s tendency to twist or turn. Several terminologies such as the moment of force or moment are alternatively utilized for describing torque.

Types of Torque

Normally two types of torque are generally noticed. The two types of Torque that are most commonly observed include dynamic torque and static torque. Firstly, static torque is defined as the torque that is not seen to produce any angular acceleration. In this context, a few examples of static torque can be mentioned. 

• When a person is pushing a door that is closed, he or she is applying a force that is static because although the person is applying the force, the door is not rotating. 
• Another example in this context is the pedaling of a cycle at a rather constant speed. Here, although the cyclist is applying a force for driving the cycle, there is no increase in acceleration and so it can be regarded as static torque. 

Next, from the name itself, it is clear that dynamic torque is the torque that is seen to produce some angular acceleration with time. Some instances of dynamic acceleration can be mentioned in this regard. If we consider a racing car that is slowly accelerating from the starting line then the drive shaft within the racing car is seen to exhibit dynamic torque. This is because the drive shaft must be creating some angular acceleration within the wheels of the racing car which is causing the whole car to accelerate slowly along the race track. 

Examples of Torque 

Torque is an important concept in physics. Several examples concerning this have been outlined in the following. 

• Gyroscope: These are devices that are used for orientation or navigation. Planes and ships mostly utilize them for steering. Vehicles that launch into space, ballistic vehicles as well as orbiting satellites are found to rely upon them. Torque forces are specifically seen to be created within the gyroscope’s spinning part. 
• Seesaw: A seesaw can be described as a plank, whose middle particularly rests on given support and functions in the form of a pivot. At the time when two individuals are sitting on the two sides of the seesaw, they are applying a torque force which ultimately causes the plank to pivot. Determination of the torque force is done based on the persons’ weight as well as the distance at which both of them are seated from the center.
• Tap turning: At the time of closing or opening a particular water tap a person’s hand turns the handle thereby applying a rotational force or torque. The pivot point is the screw or joint area on which the tap rotates. It can be seen that if the handle is small or short then operating the tap becomes particularly hard.

Conclusion

Throughout the article, several vital concepts of torque in physics have been discussed. Studying torque is very important in the subject of agricultural engineering. Torque is essentially a force that causes an object to acquire rotational motion. This means that the torque is linear forces rotational equivalent. To further discuss this, the different types of torque have been analyzed which have been properly assessed through providing some torque examples.
