Conclusion
1. For which mechanism was it the easiest to determine the mechanical advantage ordrive ratio? Why was it the easiest?
A: Pulley because it has set IMA's
2. For which mechanism was it the most difficult to determine the mechanical advantage or drive ratio? Why was it the most difficult?
A: The wheel and axle because i have a hard time with those
3. At what value would you estimate the input and output forces of your compound machine? How did you arrive at your estimated values?
A: maybe .2lb: 5lb; holding both objects
4. What modifications could you make to your compound machine to make it more mechanically efficient?
A: Change the design all together

2.4.1 West Point Bridge Design
Procedure
Structural Engineering is the design of structural elements and their connections that work together to support loads and maintain stability within a system. Structures vary by application and can range in scale from complex bridge designs to mass-produced cell phone enclosures. Regardless of the structure’s scale or purpose, all structures are designed to meet specific design criteria, including operational environment, durability, aesthetics, internal and external load handling, and cost. To ensure that the optimal structural design is achieved engineers with diverse backgrounds (e.g., material science, statics, etc.) work together throughout the design process. To aid engineers in the development of complex structural design, computer-aided design packages are used for design analysis and verification.
