Bowed tendon SDFT or DDFT in a hindleg. When the SDFT is damaged, there is a thickening of the tendon, giving it a bowed appearance when the leg is viewed from the side. Bows usually occur in the middle of the tendon region, although they may also be seen in the upper third, right below the knee or hock (high bows), and lower third, just above the fetlock (low bows). Excessive strain on a tendon can damage its collagen fibers. This is most commonly seen in performance horses that gallop or jump, who usually strain a tendon as a result of fetlock
Elastic and inelastic collisions apparatus of the Museo Galileo in Florence. Elastic and inelastic collisions apparatus The elastic and inelastic collisions apparatus is a large apparatus to study elastic and inelastic collisions. It consists of a large frame carrying two beams from which two rows of six and two wooden balls, respectively, are suspended from pairs of strings. The instrument was often used with two elastic balls (of ivory) or inelastic balls (of wet clay), of equal or different mass. By changing the parameters of the experiments such as height of fall and mass, one could conduct a systematic investigation of collision-related phenomena. For example,
