The dynamic tests run the input of the different drive units at a given speed using a motor, while measuring the input power. At the same time, a dynamometer loads the output of the drive unit while measuring the output power. A bench-mounting base unit forms the main part of this set of products. Supplied with a three-shaft gear drive unit as standard, the base unit dynamically tests the gear drive and the other optional drive units. Includes simple tools needed to fit the drive units to the base unit, and to adjust the compound gear drive. In the base units upper level, the student fits their choice of drive unit. Students use the measurements to find the performance and efficiency of the drive unit. Students may set the gear unit (supplied) as a simple or compound drive by sliding a gear in or out of mesh on the third shaft. A variable-speed, low-voltage motor provides the shaft input turning force (effort) to the drive. A dynamometer provides the output braking force (load) to the drive. Fans provide air cooling for both the motor and dynamometer. Flexible couplings with collets connect the drive unit to the motor and dynamometer for quick and accurate alignment. The dynamometer uses electromagnetic braking and a hysteresis effect to provide a variable load at a constant torque irrespective of the speed. Sensors on the motor and dynamometer measure their shaft speed, torque and therefore power in and out at the drive.

The Centrifugal Pumps Study Unit is supplied in four different versions, the first two of which allow also for series-parallel tests:
One pump with a.c. motor
One pump with d.c. motor
Two pumps with 2-speed a.c. motors
Two pumps with one 2-speed a.c. motor and one d.c. motor
Pyramidal Balance can be divided into two main groups: internal and external. The group names are derived from their location relative to the test model and wind tunnel test section internal balances reside inside a test model, while external balances reside outside the test section. During the early years of wind tunnel testing, Forces and Moments were literally measured through pan-type balances. Although technology has advanced dramatically since those early days, the term balance is still applied to the devices used for Force and Moment measurements today.

Resistance dynamometers combined with model clamp are of the same general type, but with different capacity. They are also used during propulsion tests with ship models for applying force in addition to the propeller thrust, which is often necessary for the test program. They are designed for the measurement of resistance of ship models, which are towed by a towing carriage.
