Problem 3. The stress tensor has the following form: σij [80 3 02 0 13 0 16 Check if stresses {2, 7, 17} are principal stresses for this stress tensor.

If the weight of the container is 100kg. What a ere the tensions of cables AB, AC, and AD   Also how do you know the coordinates. How do you know if they are negative or positive? Please explain why they are negative or positive and how do you find them(the coordinates)

The force shown in the figure (Eigure 1) moves an object from -010 -0.75 1. Figure Force, F (N) 0.8/ 0.6 0.4- 0.2 0 0.25 0.50 Position, x (m) 0.75 1 of 1 ▼ How much work is done by the force? Express your answer using two significant figures. View Available Hint(s) ΠΡΕΙ ΑΣΦΑ + W Submit Part B ?
