(i) the normal and shear stress on a plane inclined at an angle of 20° with the tensile stress
3. i) ii) iii)
(ii) the maximum shear stress on the plane.

Negative 5 1/12 + negative 4 1/4 + 6 3/4

Find the solution of this system of equation -7x+y=-20 9x-3y=36

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
