ECI 130 - Spring 08 - Holland Final (Open Book, Open Notes)
Name:
1. A cantilever beam of constant E and I is subjected to an unknown force or couple at end B. The equation for the elastic curve (i.e., the deflection) is given as v = -(- 22.5 x 2 ) (ft) .

Special Note on Slope-Deflection and Fixed End Moments
It is important to realize that the Slope-Deflection equations implicitly contain the relative linear displacement term, . The fixed end moment for the near end (N = near end F = far end) of a beam se

Take-Home Quiz 8 (Due 3/11/2015)
General quiz instructions: The following quiz problem is roughly representative of the difficulty of an
exam problem and should take approximately 30 minutes to complete. Having done the homework, you
should be prepared wi

Homework 8: Use slope-deflection method
1. Draw the shear and moment diagrams for the beam. Partial answer: MA = 100 kN-m (cw)
2. Draw the shear and moment diagrams for the beam if the support at B settles 0.5 in. Partial
answer: MA = 320.4 k-ft (ccw)
3.

Homework 7
1. No loads are acting on the beam, but the support at A settles 0.5 in while the support at C
settles 0.75 in. Draw the shear and moment diagrams for the beam. E= 29000 ksi and I=150 in.
Partial answer: Cy = 0.559 k (down)
2. Draw the shear an
