I took a class called Intro to Engineering Design during undergad. It was meant to be almost a practice run for the capstone course. Our project was to create a device that worked like a lawn mower to shovel snow and dispense the snow salt at the same time. One of the sub projects was to build the frame and another was to make the mechanism to dispense the salt. When the time came to integrate all of the parts together the salt dispenser was a little too long to properly fit underneath the frame. Due to the fact that the dispenser was made of pvc pipe we had an easy fix which was to cut the pipe. We took a quarter of an inch off of each side and then installed it into the frame.
