The apparatus is designed for studying motion and operation of Porter, Proell and Hartnell governors.

The equipment consists of a motor with flange for attachment of governor, speed controller with sensor and indicator, governors with shaft scale for lift measurement and weights. A guard with transparent front and top is provided for safety.

Instruction manual is also included.

The apparatus is used for studying the relationship between centrifugal force, rotating mass and its distance from the axis of rotation. Each factor can be investigated separately.

The apparatus consists of a drive motor with a speed controller, a frame for rotating arm, masses, and instruments for measurement of centrifugal force and speed. The frame is driven by a motor via a belt. The centrifugal force from a known mass on the arm is transmitted via a lever to a load cell located above the frame. A guard with transparent front is provided for safety.

Instruction manual is also included.

The apparatus is used for studying relationship between gyroscopic torque, rotor speed and rate of precession.

The equipment consists of a rotor with a motor, and a low voltage power supply and speed control. The rotor is mounted horizontally on a frame with two bearing supports. The rods with sliding weights are attached to the frame along the rotor axis to produce balance, positive or negative torque conditions. A tachometer measures rotor and progression speeds. The frame rests on a vertical shaft on bearings to permit progression. A guard with transparent front is provided for safety.

The top assembly can be removed for determination experimentally the moment of inertia, and nutation study.

Instruction manual is also included.

The apparatus is used for studying relationship between gyroscopic torque, rotor speed and rate of precession.

The equipment consists of a steel rotor with a small motor, counter weight, precession motor, and instruments for measurement of speeds and counter weight distance.  The rotor is mounted horizontally on a frame with two bearing supports. The frame has a horizontal screw for installation of counter weight to provide a torque. The frame rests on a vertical shaft driven by the precession motor. A guard with transparent front is provided for safety.

Instruction manual is also included.

This is a bench top apparatus for determination of sliding friction coefficient using an oscillating bar.

A round bar is placed on two counter turning pulleys driven by a variable speed motor with gear reducer. The distance between the two pulleys is adjustable.  Measuring instruments for pulley speed and oscillation period are provided.

Instruction manual is also included.

This apparatus is for demonstration of simple balancing techniques.

It consists of a balanced steel shaft mounted on two self-aligned ball bearings on a rigid frame with rubber footings to minimize vibration. Four different balance masses, which can be easily clamped on any position on the shaft are provided.

For static balancing, an extension shaft with a pulley is fitted to one end of the shaft. Two weight containers with a cord are wound around the pulley. Steel balls are then added to one container until the shaft is in equilibrium to determine the maximum moment of each balance mass. An angular scale is attached to the other end of the shaft and a linear scale is attached along the frame parallel to the shaft to measure angular and linear positions of each mass.

For dynamic balancing, the shaft assembly is driven by a fixed speed motor via a belt. In the case of unbalance, the shaft will vibrate and the vibration is absorbed on the rubber footings. A safety guard with transparent front is provided.

Instruction manual is also included.

The machine is used for studying of balancing principles.

A rotor shaft is connected to the motor by a double universal joint and rests on two supports with adjustable distance between supports. Each support holds the shaft in place by three bearings with crest. Two standard rotors and two radially slotted rotors are provided for various cases of balancing. The unbalance forces are picked up by two vibration transducers and converted to digital signals. The speed is adjusted by an inverter and speed signal is provided by a sensor. The magnitude and angle of the unbalance for each plane is analyzed and displayed on a computer (separately supplied). The vibration and speed transducers are removable for field use. A note book computer is recommended for field use but is not included in the scope of supply. A transparent cover is provided for safety.
