Torque testing is used to measure the force to turn something. Some every day examples could be the force needed to turn the steering wheel in your car, or how much effort you would require to open a glass of jam or container of milk.
Torque Testing Measurement
There are generally two approaches to measure breakaway the torque. The first method measures the torque required to turn a part, the other method measures the torques required to prevent a part from rotating. The other type is running torque, this is the required torque to keep a part rotating at a constant angular velocity.
Usage of Toque Test
Torque test is used in a lot of applications across industries, and a few examples are outlined below.
- For a large construction there can be thousands of fasteners used, and it could have catastrophic consequences if some of them failed. For example if a given part is held in place by 6 fasteners and 3 of them aren’t properly tightened, the part could potentially fall down as it was not designed to be held in only 3 points.
- A cylinder head on an engine is tightened with a given torque on each bolt at the garage if you have the top gasket changed. If they are not tightened to a certain level you risk the bolts become loose or it does not seal properly between the parts.
- If the toque to open the lid on water bottle is not controlled in the factory producing them, they might end up with a lot of complains from costumers not able to open them. Or even worse, they will start buying the competitors product instead.
