Linear Slider 

Linear Slides can be subject to jamming (like screen doors). This is the reason many designers prefer rotary pivots whenever possible. However, if one would like to build a linear slide that does not jam, one needs to understand the reasons behind jamming.

In this assignment each student will analyze a Linear Slider, which is similar to the one shown in lecture. The overall objective of the assignment is to identify how to build good Linear Sliders that do not jam, and to develop skills in applying Free Body Diagrams (FBD). But do NOT forget, it is often better to replace a linear bearing with a rotary bearing when possible.
