Fatigue Testing Machine - Multiple Sheet Flexure, Aeronautical Research Laboratories (ARL), 1945 Object Reg. No: HT 26594

The Multiple Sheet Flexure Fatigue Machine was designed and made by ARL. It is a constant strain mechanical type machine in which up to 12 metal sheet specimens may be tested simultaneously in bending under zero mean load conditions at a testing speed of 2140 CPM. The capacity of the machine is 50 lb per specimen. The machine is driven by a Brooke Motors SC7.637671, 1.75 HP, 3-phase electric motor. There is a Veeder Root counter for each specimen to record the number of cycles before failure at which point the counter stops. The final plan drawing for this machine was signed off on 6 August 1945. There is a typed instruction manual compiled by John Y. Mann with the machine dated December 1953. It is mounted on a wooden cabinet containing the electric motor with mesh sides for cooling.
