FINAL EXAM
OPEN BOOK, CLOSED NOTES, SHOW ALL WORK FOR PARTIAL CREDIT
Problem 1: (10 points) For the beam and loading shown, draw the shear and bending-moment diagrams, and
determine the maximum absolute values of the shear and bending moment.
Problem 2: (10 points) Two 8° wedges of negligible weight are used to move and position the 800-block.
Knowing that the coefficient of static friction is 0.30 at all surfaces of contact, determine the smallest force P
that should be applied.
Problems 3 is on the back of this sheet.
