A general three-dimensional load is applied to a structure which results in a general three-dimensional stress state (left view). Using the eigenvalue approach, the three principal stresses are found to be ( σp1 = 3.3, σp2 = 8.5, σp3 = 24.9 ), (see right view), where the eigenvectors determine the orientation of (1,2,3) relative to the original (x, y,z) frame. If this element, in the principal frame (1,2,3), is rotated (45o) CCW about the positive (2-axis), then shear stresses will be produced on some or all of the three element faces. What is the magnitude of the largest of these three possible shear stresses?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
