Theoretical strength formula
For a rectangular sample under a load in a three-point bending setup (Fig. 3): • F is the load (force) at the fracture point (N) • L is the length of the support span • b is width Webb24 jan. 2024 · Whenever we lift weights, we are exerting force against the barbell. In physics, we measure force using Newton’s Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both).
