What is the difference between a static and a dynamic analysis? (5 pts.) 2. What two basic approaches are used by designers to increase impact resistance? (5 pts.) 3. Name several design features that can affect fatigue failure in a plastic part. (5 pts.) 4. Example 4.4 uses composite beam analysis by factoring the difference in material modulus of elasticity between the two materials times the width of the paint layer to "equalize" the materials in the composite. a. Would increasing the relative thickness of the material be equivalent? (5 pts.) b. There is a 12% error by not including the paint layer in the analysis, can you prove this? (45 pts.) For reference see Example 4.3 and Session 6d for the analysis technique for composite beams. 5. Other than adding ribs, what else could you do to add stiffness to a product (5 pts.) 6. At the root of a cantilever beam snap finger, with a thickness of 2 mm and a fillet radius of 1 mm, what stress concentration factor would be expected (5 pts.) 7. Our company wants to replace a 25 mm O.D., 23 mm I.D. glass filled ABS tube extrusion, made from AIE 20G4F with
