2 Addition to Exam #2 grade
Quiz! You have 30 minutes Addition to Exam #2 grade Apply points on worst problem As many as ½ points lost Can only improve score

3 Upcoming Schedule Today Wed. - Fluid Statics (out of order)
Shear & Moment diagrams (cont.) Info on Group Design Project Wed. - Fluid Statics (out of order) Next Mon. - Flexible Cables (out of order) What’s left? Friction Area Moments of Inertia

4 Shear & Moment Diagrams
Went over the most robust method Free body diagrams at each segment Use equations to calculate V & M values “Shortcut” Use relations between slope, area Faster, graphical route to same answers
