With reference to the crinkled type of radiator, I think it would be as well to repeat the bumping with two radiators, one with the balls well underneath, and the other with the rough method of support. The difference between 11 1/2 hours and 14 hours is not sufficient in one experiment to be conclusive. Do you know whether any of those radiators in which the spheres have been well underneath, have failed on the road ? It would be interesting also to push forward the experiments with the trunnions on the side plates as suggested, so as to take the whole of the supporting of the radiator off the crinkled tubes. It possibly happens that the chief cause of stress is the radiator being thrown sideways causing it to become slightly this shape. [Hand-drawn sketch of a radiator with X-shaped bracing] Could you temporarily stay it as shown by the X front and back to see whether it made any difference. F.H.R. | ||
