Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Concerned that the force may be too strong

    • Try using a smaller spring force, disengaging the spring, or having to springs activating at separate points

  • Use telescoping tubes for the final to makes lengths adjustable and more durable

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Prototype needs refinement for testing

  • If spring force is too much, lower the force and user test to see if it works
