Order CV Half Shaft for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. In reality, the tensile and compressive strengths of carbon fiber are not the same, and the half shaft is typically loaded in one direction (accelerating) more highly than the other (engine braking). A graph such as this will show you which force is developed at a particular speed and this for compression and extension (bump or rebound). Half shafts are commonly designed by predicting the applied torsional loads and selecting inner and outer diameters to not exceed the material's yield strength. Quantity. Basic Design Features 24 b.
