Unformatted text preview: <5 1 ME222 Final Exam (August 18, 2006) NAME l. The beam shown below is fixed at both ends. In order to determine the deﬂection
equation y(x) of the beam, the following questions should be answered. (a) Draw a FBD
with all unknowns. (b) Give the equilibrium equations. (c) Based on a simplysupported
beam, draw diagrams to show the exercise of the principle of superposition. (d) Give the
deformation equations (in terms of y and/or y ’) required for identifying the unknowns. (e)
Express the deformation equations in terms of forces. (f) Find the reaction forces, if the
bending rigidity E1 is constant through the length of the beam. (g) Draw the shearforce
and bendingmoment diagrams. Identify the maxima and minima on the diagrams. (6)
Grading will be primarily based on (f) and (g). (53% p y 2. Repeat (C)(f) of Problem 1 based on a cantilevered beam. ex x; 3. A cantilevered beam shown below is ﬁxed at one end and attached by a 6” bracket (on
