16.20 Handed Out: Lecture 41 Due: Lecture 46 HOME ASSIGNMENT #10 Warm-Up Exercises A perfect column of length L has constant cross-sectional properties equal to EI. Each end of the column is held by a torsional spring of stiffness k T . The overall configuration is depicted below with the open circle representing the torsional spring. z x L k T P k T 1. Determine the equation to be solved to find the buckling load P cr (simplify as much as possible). 2. Consider the limiting case where the torsional constant goes to 0 and find the actual buckling load P cr . Identify the simple configuration that has the same buckling load. Explain, from physical considerations, why this must be so. 3. Consider the limiting case where the torsional constant goes to and find the actual buckling load P cr .
