If the tension-loaded plate of Fig. 3-29 is infinitely wide, then the stress state anywhere in the plate can be described in polar coordinates as

For the radial, tangential, and shear components, respectively. Here r is the distance from the center to the point of interest and θ is measured positive counterclockwise from the horizontal axis.
(a) Find the stress components at the top and side of the hole for r = d/2.
(b) If d = 10 mm, plot a graph of the tangential stress distribution σθ /σ for θ = 90
