All results must be given to the precision used in the textbook.  Assume that the data are known to the same precision.  Thus, when a value of 2 kips is given, it is assumed that it is known to 3 digits; i.e., 2.00 kips.  You may receive partial credit if you show your work (on the reverse).  The units requested must be given with all answers. Print this page and write the answers in the blanks.  Sign the statement at the bottom.  Then submit the page before class on Monday.

1. The bending moment for a certain beam is plotted.  The values vary from a positive 30 kN-m to a negative 45 kN-m.  For the purposes of computing the maximum normal stress due to bending, what value of the bending moment is used?	45 kN-m
2. The required section modulus Sx for a structural steel W-beam is 16.1 in3.  What is the least expensive W-beam that can be chosen?	W 12 x 16
3. For a 12 m long beam, a concentrated load of 5 kN down is applied at the midpoint.  Aside from the other portions of the shear function, write that portion of the shear function that accounts for this concentrated load.
4. Compute the following function at x = 3 and x = 6 m (two answers):	13, 23
5. True or False?  The use of singularity functions permits the determination of the position of a maximum bending moment depite the presence of a discontinuity at the position of that maximum moment. (circle one)	False

I certify that I have not spent more than 15 minutes on the above quiz, that I did not discuss it with someone else, and that I received no help from another person.
