Solved: A 250-m-long bridge is improperly designed so that
Chapter , Problem 62(choose chapter or problem)
A 250-m-long bridge is improperly designed so that it cannot expand with temperature. It is made of con crete with a 5 12 3 1026 C21. (a) Assuming the maximum change in temperature at the site is expected to be 20C, find the change in length the span would undergo if it were free to expand. (b) Show that the stress on an object with Youngs modulus Y when raised by DT with its ends firmly fixed is given by aY DT. (c) If the maximum stress the bridge can withstand without crumbling is 2.0 3 107 Pa, will it crumble because of this temperature increase? Youngs modulus for concrete is about 2.0 3 1010 Pa.
