Homework Help: Shear Stress Due to Angular Deceleration

I have a rectangular block (propellar) with known width, thickness, legth, and uniform density. It is spinning at a constant angular velocity around its centroid. Then it is decelerated at a constant rate to rest. I want to find the relation between the radial distance from the centroid and the shear stress during the decelleration, so that I can determine the maximum shear stress. Please help! Thanks!
