Balance with Weights
Subject
The topic of the resource
Measurement of Weight
Description
An account of the resource
<strong>The simplest type of balance, the equal-arm, or beam, balance, is an application of a lever. A uniform bar, the beam, is suspended at its exact center on a knife-edge set at right angles to it. The point of support is called the fulcrum. Two pans of equal weight are suspended from the beam, one at each end, at points equidistant from the fulcrum. The object to be weighed is placed on one pan, and standard weights are added to the other until the balance of the beam is established again. The unknown weight can then be determined by adding up the standard weights in the pan.</strong>

Fountain in a Vacuum
Subject

Pneumatics
Description
An account of the resource
<p><strong>"The “Fountain in Vacuo” is a perfectly delightful and entertaining 19th century demonstration that is never done today. Volume 1 of Pike’s Illustrated Catalogue of Optical, Mathematical and Philosophical Instruments (New York, 1856) describes it, “The fountain consists of a tall receiver, of glass, about five inches wide in the swell, but contracted at the top, and cemented by a neck at the lower end to a brass cap, having within a jet pipe attached to a stop-cock, which screws into the cap; the whole is mounted on a stand when not in use. To use, the fountain is connected with the air pump by means of the stop-cock and tube; after the air is exhausted out of the receiver, the cock is shut to prevent its return; then the whole is unscrewed from the plate of the receiver, and the lower end of the tub is immersed in a vessel of water; on opening the stop-cock, the pressure of the atmosphere on the surface of the water in the vessel having not counterpoise from the interior of the cylinder, forces up the fluid through the jet-pipe with considerable velocity, which forms a pleasing jet-d’eau, or fountain in vacuo. Price $4.50; larger $5.00”.</strong></p>

Just to the left of it is the Kelvin current balance still in the possession of the department. A little more to the left is a differential galvanometer , easily recognized by the circular compensation bar across its top. An induction coil can be seen in the middle of the picture, and at the the left is Wiedemann's galvanometer (electrotome), sitting on a brick pier to eliminate vibrations. In the foreground is a telescope and scale for reading the galvanometer. To the right of the left door sits an ammeter. Many of these instruments are still at W&L and are listed in this exhibit.<br /></strong>
