This week we had to redesign the majority of the pedal box
due to the placement of the steering rack and pinion being overlooked and partially
due to the team’s inexperience with Formula SAE racecars. When doing the
redesign, as seen in Figure 1, the team had to go back to the drawing board and take new
measurements. After doing so the next step was to create another pedal box with
nearly all new sized pieces. The main structure will be machined from a 0.625”
thick plate of 6061-T6 aluminum that is 8” wide by 13.25” long. All of the
other pieces will also be constructed out of the same material as the main
structure. The total calculated weight is said to be 5.95 pounds which is a 2.84-pound
savings from the previous design. In the end this redesign set the group back
approximately a week.
