-2- by the variation in the re-action (acting on the mass of the engine) due to the varying torque on the crankshaft. You will understand that these investigations are necessarily long and tedious, but I will issue a detailed report as soon as possible. I think the matter is of great importance, and there is no doubt that it is the same vibration as Mr Royce speaks of as occuring at 20 m.p.h. on previous chassis. | ||
