Scales Rulers
Scales or rulers are considered as a narrow, flat object with straight edges you can use to draw straight lines and having marks you can use to measure things. It is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure or draw straight lines. Scales are considered as one of the important parts of a stationary in any office or industry. These are the kinds of stationary devices or tools which are used for drawing up lines and measuring purposes. The applications of these tools can only be so much since there is no other reason to be able to use elsewhere. The scales vary in sizes and can be really long as well. The smaller versions of these scales are used for daily activities and needs on a very basic level.
