In order to understand rotation and tourque, you need to understand the movement of force. Basically torque is the amount of force must be used on an object to strain it to turn on its axis. If you think of force as the ability to push or pull an object, you can think or torque as the ability to rotate an object. In Match, torque is defined as an the relationship between force, linear movement and angular movement without the consideration of gravity and friction. It’s basically, a way to measure the turning force of something. Think about tools: you can push or pull a wrench handle that is fixed around a nut in order to loosen or tighten the nut. That motion of loosening and tightening produces rotation and tourque.

Generally speaking, there is a center of mass for everything. If you apply pressure or force to the center of mass, the whole object will move. However, if you apply the force at either end and the center of mass was a fixed point, the object would rotate around the center of mass or pivot point. Torque is force times distance. Here the force is perpendicular to the object. The force measurements are done in newtons and distance is measured in meters.

Now, understanding rotation and tourque is important to understanding properly how the body and the planet functions but it can be useful in day to day life as well. For example, now you can efficiently use a torque wrench knowing what exactly it can do. Typically, nuts and bolts that need to be tightened to a particular load will require a torque wrench. If you stretch or break these kinds of nuts or bolts they will become useless and can possible damage the item they were on.

A torque wrench used the rotation and tourque methods in order to apply a known amount of pressure to a bolt or a nut. You control the amount of force than is applied by how much you push or pull on the handle of the wrench. The longer that the tool is, the more leverage effect and torque you will be applying. Most torque wrenches will have a display screen so that you can see exactly how much load is being applied. The appropriate amount is directly linked to how long the wrench is. For example, a single foot pound equals out to 12 inch pounds and 1.3558 Newton Meters. 1 Nm is 1/7375 foot pounds and one inch pound is 0.1129 Nm.

In order to get the right amount of torque, you have to make sure that you are holding the tool right along the grip and push only the handle. Some wrenches have a pivot point and if so, then the load needs to be balanced over that point. Socket wrenches can be used in conjunction with torque wrenches but first make sure that the extension is parallel to the fastener.

There are several types of torque wrenches that are available. The four most common types are the beam style, adjustable, dial gauge and digital. The beam style wrench is the most inexpensive and readily available type of wrench, going for no more than $30 at any given hardware store. However, the adjustable click wrench is quicker and tends to be more accurate, making it the chosen wrench for professionals.

If you are going to be using one of the torque wrenches then you need to ensure that it is properly calibrated and read for use otherwise the readings could be off and give you an incorrect measurement reading. This will result in broken bolts and objects. You may need other types of tools in order to help you in the process such as an angle gauge and others. An angle gauge is fairly simple to use but you must make sure that the pointer is on zero and then you can use it to take note of how many degrees you have rotated the fastener as you turn it.

Proper and responsible use of any type of tool will result in a job well done but if you have any hesitations, call in an expert before you end up making the problem worse!
