Abstract

The technical report presented below is based on the design of mechanism that can be used to open and shut the windows of mechanical engineering workshop from ground level .this mechanism was designed in order to improve safety and convince in their workshop .in the report, the design analysis were made and materials were selected based on operating conditions of each component.
The material of the tilt and turn mechanism is cast iron while the material of the lever (handle) is stainless steel. The cost analysis was also done in order to verify the total cost that will be incurred in the construction process.

Introduction

The word window originates from the Old Norse 'vindauga', from 'vindwind' and 'auga–eye', i.e., wind eye. In Norwegian Nynorsk and Icelandic the Old Norse form has survived to this day (in Icelandic only as a less used synonym to gluggi), in Swedish the word vindöga remains as a term for a hole through the roof of a hut, and in the Danish language 'vindue' and Norwegian Bokmål 'vindu', the direct link to 'eye' is lost, just like for 'window'. The Danish (but not the Bokmål) word is pronounced fairly similarly to window. Window is first recorded in the early 13th century, and originally referred to an unglazed hole in a roof. Window replaced the Old English eagþyrl, which literally means 'eye-hole,' and 'eagduru' 'eye-door'. Many Germanic languages however adopted the Latin word 'fenestra' to describe a window with glass, such as standard Swedish 'fönster', or German 'Fenster'. The use of window in English is probably because of the Scandinavian influence on the English language by means of loanwords during the Viking Age. In English the word fenester was used as a parallel until the mid-18th century and fenestration is still used to describe the arrangement of windows within a façade. Also, words such as "defenestration" are in use, meaning to throw something out of a window. From Webster's 1828 Dictionary: Window, n. [G. The vulgar pronunciation is windor, as if from the Welsh, wind-door.
