What is torque?
Torque is defined as a force that causes an object to spin around a rotational axis, often referred to as a 'twisting force' or rotational force. It is an essential concept in both physics and engineering, and is crucial for understanding how engines, motors, and machinery operate.

The driveshaft in a vehicle is perhaps the most common example of torque in action, as the amount of torque generated by the engine directly impacts the vehicle's performance. Torque is a vector quantity, which means it has both a direction and magnitude.
In practical terms, torque can be seen in various applications, including the turning of screws, bolts, and gears, where it's essential to use the correct amount of torque to ensure the proper function of the assembly.
Why do we need to measure torque?
Measuring torque accurately is critical when designing and troubleshooting mechanical systems, as it helps understand the performance and integrity of rotating parts. Precise torque measurements can prevent system failures and allow for predictive maintenance strategies, ensuring machinery operates within safe limits.
What are the main types of torque?
There are two main types of torque: rotary torque and reaction torque:
Rotary torque (rotational/dynamic torque)
Reaction torque (static torque)
How is torque measured?
Torque can be measured through both indirect and direct methods. Indirect measurement typically involves using a power meter to estimate torque, while direct measurement utilizes specialized sensors designed to gauge torque with greater accuracy.
Reaction (static) torque sensors
A common example of a reaction torque sensor is a torque wrench, which provides audible or visual indications when the desired torque is reached. Digital torque wrenches enhance accuracy by displaying the applied torque in real-time.
Rotational (dynamic) torque sensors
Rotational torque sensors are transducers that measure the torque of rotating devices and are commonly used in applications like motor testing and equipment validation.
Order analysis applications
Torsional vibration in machinery can lead to significant issues if not monitored and managed effectively, making torque measurement vital for maintenance and performance optimization.
What is torsional vibration?
Torsional vibration refers to the oscillations of an object around its axis of rotation, which can result from changes in applied torque or variations in load.
Summary
Torque sensors, including both rotary and reaction types, are widely used across various industries. They play a critical role in automotive, aerospace, and manufacturing applications, ensuring performance and safety.
