Will you please measure for us the torsional rigidity in the crankcase and the polar moment of inertia of this crankshaft while the engine is stripped. We also want to know the weight of the bars camshaft brakes and the load with which they are held onto the stationary drum. This is to enable us to calculate at what speed they cease to operate.
