Determine the maximum in-plane shear stress developed at point A on the cross section of the arm at section a-a. Point A is located on the web of the I beam, immediately below the flange. Please use the shear formula when calculating the shear stress, T. (See chapter 7 of the textbook if you're unsure). The question is asking for the maximum in-plane shear stress, you can use Mohr's circle to determine this, once you have calculated the stresses at Point A.
