A point in a structural member is subjected to plane strain. Determine the average normal strain associated with the maximum shear strain in the x-y plane.εx = –120 μεεy = –250 μεγxy = –70 μrad

An upward load is applied to a circular rod that has a diameter of 10.55 mm. The rod is connected to the ground using a pin that has a diameter of 9.57 mm. If the normal stress in the rod is limited to 295 MPa and the average shear stress in the pin is limited to 135 MPa, determine the maximum load that can be applied to this connection.
