- Leonardo da Vinci (1452–1519) is creditedwith being the first to perform quantitative experiments on friction, though his results weren’t known until centuries later, due inpart to the secret code (mirror writing) he used in his notebooks.Leonardo would place a block of wood on an inclined plane andmeasure the angle at which the block begins to slide. He reportsthat the coefficient of static friction was 0.25 in his experiments.At what angle did Leonardo’s blocks begin to slide?Please answer asap. Thumbs up if correct.
