Practice Problem 6-4 (a) | Back | Index | Next |
Given: A steel beam (E = 30 Msi) of length L = 30 in. has a square cross-section (2 in. by 2 in.). The beam is simply supported at the left end and has a guided support at the right end. A load of P = 200 lb is applied a the the right end. Req'd: Determine the Moment of Inertia I of the beam. |
Sol'n: The moment of inertia for a square beam is: I = t^{4}/12 = (2 in.)^{4}/12 I = 1.33 in^{4} |
