vääntömomentiksi

Vääntömomentiksi, also known as torque, is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. The direction of the torque is perpendicular to the plane formed by the force and the axis of rotation, as determined by the right-hand rule.

The magnitude of torque can be calculated using the formula T = r × F, where T is the torque, r is the lever arm (the perpendicular distance from the axis of rotation to the line of action of the force), and F is the force applied. Alternatively, torque can be expressed as T = Iα, where I is the moment of inertia and α is the angular acceleration.

Torque is a fundamental concept in physics and engineering, with applications ranging from mechanical systems to electrical motors. It is used to describe the rotational equivalent of linear force, and is crucial in understanding the behavior of rotating objects. In everyday life, torque is often encountered in activities such as turning a doorknob or pedaling a bicycle.
