Determine (a) the principal stresses and (b) the maximum in-plane shear stress/average normal stress that are developed at point a. draw the ‘little red squares’ for both situations. use mohr’s circle(s) only.

What are the three ways that an object can accelerate

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k
