1. Let $A = \begin{bmatrix} -2 & 1\\ 0 & 1 \end{bmatrix}$ Find all 2x2 matrices $B$ with the property that $AB = BA$. [Hint: if you find a matrix $B$ with this property, then all multiples of $B$ will have the property.] That gives you a "degree of freedom" -- set a suitable variable equal to 1 at some point.]

6. (30%) Mohr's circle is shown in Fig. 6 for a point in a physical object that is subjected to plane stress. (a). Determine the stresses $\sigma_{xx}$, $\sigma_{yy}$ and $\tau_{xy} (\sigma_{xy})$ and show them on a stress element. (b). Determine the stresses $\sigma_{nn}$, $\sigma_{tt}$ and $\tau_{nt} (\sigma_{nt})$ and show them on a stress element that is properly rotated with respect to the x-y element. The sketch must include the magnitude of the angle between the x and n axes and an indication of the rotation direction (i.e., either clockwise or counterclockwise).

From a height of 4 m, a hollow sphere with a radius of 12 cm and a mass of 650 g rolls along an inclined trough (45° to the horizon). The system is located on Earth. [1] Find the potential [2] and [3] the kinetic energy at $t_0$ just before the start of rolling and at the end of the slope of $t_f$. [4] Find the momentum at the end of the road. [5] How would the momentum at the end of the slope change if the sphere slipped? Assume that the sphere is rolling in a V-shape slope/track (track sides are at right angle). The image shows cross section of the sphere in the track.
