Instruction sheet

12/10 ALF

1 Axle

2 Movable cylinder

3 Lever arm

4 Coil spring

5 Flyweight arms with counterweights

1. Safety instructions

Danger of injury owing to the action of large cen-

trifugal forces. Therefore:

• Before starting the experiment, check whether

the

counterweights are attached firmly to the

flyweight arms.

• Insert the axle deep into the chuck of the ex-

periment motor and clamp it tight.

• Always maintain a safe distance.

• Gradually increase the angular velocity.

• Do not touch or try to hold the rotating body.

• Before dismantling, disconnect the equipment

from the mains power supply.

Long hair, loose clothing as well as jewelry could

get caught in the rotating parts and result in injury.

• To avoid this hazard, persons with long hair

should wear a hair net.

• Inappropriate clothing or jewelry should be

removed.

2. Description

Watt’s governor is used to demonstrate centrifugal

force and the principle of centrifugal speed control,

for instance in steam engines.

Two flyweight arms are centrally fitted onto an

axle. The arms are held in a state of rest by a coil

spring. When the axle rotates, the weights work

their way upwards to a degree dependent on the

speed. This movement has technical applications

for control and regulatory tasks (centrifugal regula-

tor).

3. Technical data

Maximum diameter: 350 mm

Height: 250 mm

Axle diameter: 10 mm

Weight: 0.4 kg approx.
