Question:

Beam ACB hangs from two springs, as shown in the figure. The springs have stiffnesses k1 and k2 and the beam has flexural rigidity EI.
(a) What is the downward displacement of point C, which is at the midpoint of the beam, when the moment M0 is applied? Data for the structure are as follows: M0 = 7.5 k-ft, L = 6 ft, EI = 520 k-ft2, k1 = 17 k/ft, and k2 = 11 k/ft.
(b) Repeat (a) but remove M0 and, instead, apply uniform load q over the entire beam.
