Unformatted text preview: C) A significant effect What changes in this solution If there is a gap at A? Gap or No Gap Extra Credit Using the analysis details provided in the previous example: 1. Identify a cross sectional shape and dimensions for a beam with a bending area moment of inertia close to that used in the example (248 x 10 6 mm 4 ). 2. Use this cross section to calculate maximum bending stress in the beam when there is a gap at A. 3. Compare this value to the material yield strength to determine a factor of safety. 4. Recalculate support reactions and maximum stress if a different type of building material is used (such as wood or aluminum). 5. Write a concluding statement about why you would or would not authorized the extra time and expense to eliminate the gap at A prior to loading this beam. Due in class Wednesday, April 9 th . How does this solutions change if A is supported by a deformable post?...
