Visual Perception Pictorial depth cues are what we use to create depth and distance on a 2D canvas or paper. Linear perspective is used when two parallel lines converge together and are perceived to come to a point into the distance. We perceive this in straight roads‚ railway tracks or hallways. This image displays linear perspective on the left side on the box as it is perceived to come together despite the fact that the lines are parallel. Interposition is used when an object sits in front

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they
