Calculating the force and stress on a hip joint during walking or running involves estimating the impact force upon contact with the ground and dividing it by the cross-sectional area of the joint. The challenge lies in the variability of these forces due to individual differences in body mass. A simple approach is suggested for a presentation, focusing on approximations rather than precise calculations. Input from others is sought to refine these estimates and understand the relevant forces and timescales. Overall, the discussion emphasizes the need for basic calculations while acknowledging the complexities involved.
