1A20.42 - Large Scale Slide Rule
Large Scale Slide Rule for demonstration purposes and easy viewership.
Pull down the large scale Slide Rule from the ceiling in room 80. Be sure to clean off the dust prior to use. If the demo is being used in the lecture hall, remove the pink string so that the slide rule can move freely. If the demo is being exported, be sure to explain to the lecturer how to remove and reattach the pink string before travel in order to keep the slide rule from extending out while in transport.
Use this demonstration sized slide rule to explain how a slide rule works. If you are exporting this item, be sure to remove the pink anti-slide string prior to use and to replace the string prior to transportation.
