The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation
Sports biomechanics is the quantitative based study and analysis of athletes and sports activities in general. It can simply be described as the physics of sports. Within this specialized field of biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement.
Active assisted range of motion (or AAROM) – Patient uses the muscles surrounding the joint to perform the exercise but requires some help from the therapist or equipment (such as a strap). Active range of motion (or AROM ) – Patient performs the exercise to move the joint without any assistance to the muscles surrounding the joint.
Range of motion exercises are also called "ROM" exercises. There are three types of ROM exercises: passive, active, and active assists. Passive range of motion is movement applied to a joint solely by another person or persons or a passive motion machine. When passive range of motion is applied, the joint of an individual receiving exercise is ...
Sports engineering is a sub-discipline of engineering that applies math and science to develop technology, equipment, and other resources as they pertain to sport. Head tennis racquet Sports engineering was first introduced by Isaac Newton ’s observation of a tennis ball. [ 1 ]
An elliptical machine, a type of exercise machine. An exercise machine is any machine used for physical exercise. These range from simple spring-like devices to computerized electromechanical devices to recirculating-stream swimming pools. Most exercise machines incorporate an ergometer.

A static balance (sometimes called a force balance [2] [3]) occurs when the inertial axis of a rotating mass is displaced from and parallel to the axis of rotation.Static unbalances can occur more frequently in disk-shaped rotors because the thin geometric profile of the disk allows for an uneven distribution of mass with an inertial axis that is nearly parallel to the axis of rotation.
