The present invention is directed to a device and method for measuring forces applied to actuating elements of a musical instrument. The present invention does not alter the feel and operation of the actuating elements of the musical instrument. Therefore, authentic performances can be executed with the device of the present invention, while allowing for collection of time-dependent force data and display of this data in real-time with a graphic interface. The present invention can be used in occupational biomechanics and research on upper extremity biomechanical exposure for musicians. The information produced by a device and method according to the present invention can be used for training musicians in technique. The present invention can also be used for ergonomic assessment of instruments, playing position, playing environments, and other factors impacting playing a musical instrument.

Disclosed is a sheave for use in a tension measurement system to measure a tension force in a cable. The sheave includes a first diameter and a second diameter. The sheave is configured to rotate about an axis to orient the first diameter or the second diameter toward the cable, such that a contact force between the sheave and the cable is measured by a tension sensor to determine the tension force in the cable.

The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.
