 Force Testing

             To test the force needed to operate our design, we used a spring scale attached to the lever and measured the force needed to pull down the lever as the pill was crushed. Overall we found that a repeated, light hammering motion was most effective at crushing the pills with minimal applied force compared to applying a single large force at once. This method still allows for the grinding action to take place but prevents the pills from compacting together.
