over time repetitive axial loading will increase

Assume that the mass of the load acting on it is 10 Kg. Cyclic stress is the distribution of forces (aka stresses) that change over time in a repetitive fashion. Recent studies suggest that the onset of OA may be determined by a shift in load-bearing to less frequently loaded regions of the cartilage and subsequent progression of OA is caused . This is approximately 42% of the yield stress for compression/tension. And as you get older, it'll be wise to reduce the amount of axial loading you perform in the gym. Both these loadsradial and axialare important when studying the motion of a spinning object. But opting out of some of these cookies may have an effect on your browsing experience.
