Handed Out: Lecture 29 Due: Lecture 33 HOME ASSIGNMENT #7 Warm-Up Exercises In the last home assignment, two cross-sections were considered (a C-section and an I-section) for their torsional capabilities. The torsional constant J was determined to be 6300 mm 4 . Let’s explore what happens if we use the same amount of material (aluminum with E = 70 GPa and ν = 0.3) but close the cross- section. This is done by dividing the vertical part in half and placing it on each end of the horizontal pieces: 5.0 mm 90 mm 35 mm 2.5 mm 5.0 mm 2.5 mm 1. Determine the new torsion constant of this cross-section. 2. Determine the ratio of the angle of twist between the two end faces of the same structural configuration subjected to the same loading from the last home assignment when the current cross-section is used as compared to the previous cross-section(s). 3. Find the maximum resultant shear stress and its location. 4.
