1. Predictions of elastic modulus, yield and ultimate loads (attach additional sheets not enough space): Given: - steel tube outer diameter: 165.1mm; wall thickness: 3.3mm; no gap between concrete and steel. - Young's modulus of steel (200 GPa). Young's modulus of concrete (30 GPa). - strengths of concrete (45 MPa) and steel (yield stress q=350 MPa, ultimate stress 0,450 MPa). Calculate/Predict (see questions 9 & 10, in "stress-strain_deformation_16Questions_solutions.pdf): -Young's Modulus E of the composite material...

There is a bug sitting between the treads of your car tire. We start a short commute of 1 mile (or 5280 feet) and the bug remains a the same location between the tread of your tire without getting squished. Assume the tire is 2 feet in diameter (so the center is exactly 1 foot above the pavement) and the tread width is negligible so the bug is almost touching the road as the tire rotates. How far does the...
