The 60 mm × 60 mm oak post is supported on the pine block. If the allowable bearing stresses for these materials are σoak = 43 MPa and σpjne = 25 MPa, determine the greatest load P that can be supported. If a rigid bearing plate is used between these materials, determine its required area so that the maximum load P can be supported. What is this load?
