Strain Gauge Project

1. Strain Gauge Project LeShaun Alexander

2. Problem: • Detecting and measuring flow rates of very shallow and slow moving water requires special equipment which can be very expensive. The need to measure these flow rates is relevant to creek restoration societies locally.

5. Assigning Metrics • Objective: Lightweight • Units: Rating weight on scale from 0 (worst) to 5 (best) • Metrics: Total weight of device from 0 (more than 30lbs.) to 5 (less than 5lbs.) • Objective: Inexpensive • Units: Rating cost of materials only 0 (worst) to 5 (best) • Metrics: Total cost of materials from 0 (more than $100) to 4 (less than $25) • Objective: Large enough screen to view information • Units: Rating whether the device has a large enough screen 0 (worst) to 3 (best) • Metrics: 0 (Device has no display) to 3 (Uses graphical display)

6. Assigning Metrics (cont.) • Objective: Usable with minimal assistance • Units: Rating ease of use on scale from 0 (worst) to 3 (best) • Metrics: Ease of use from 0 (Only an engineer can use it) to 3 (anyone who can read the manual)
