Cross Member for Rubber Engine Mounting, 20/25 HP. --------------------------------------- Herewith figures comparing deflection of this cross member with and without a stiffener. Though we have run 50 hours on this member without it taking a permanent set vertically, we think it could with advantage be stiffened up a little more in this plane.
