Abstract
The crosshead for a universal testing machine includes a interior face which is formed at angle to the front face which is typically about 17°. A wedge pocket is machined with walls perpendicular to the interior face, and therefore at an angle other than perpendicular to the front surface of the crosshead. This allows a rectangular steel plate to be oriented to match the machine column locations. Therefore, the material cost is significantly reduced as no special casting shape is required.
