A roller support allows thermal expansion and contraction of the span and prevents damage on other structural members such as a pinned support. The typical application of roller supports is in large bridges. In civil engineering, roller supports can be seen at one end of a bridge. A roller support cannot prevent translational movements in ...
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...
Animals will use different gaits for different speeds, terrain, and situations. For example, horses show four natural gaits, the slowest horse gait is the walk, then there are three faster gaits which, from slowest to fastest, are the trot, the canter, and the gallop. Animals may also have unusual gaits that are used occasionally, such as for ...
A simple support (pin or roller) is equivalent to a point force on the beam which is adjusted in such a way as to fix the position of the beam at that point. A fixed support or clamp, is equivalent to the combination of a point force and a point torque which is adjusted in such a way as to fix both the position and slope of the beam at that point.
The tree provides distributed mechanical support, reducing localised mechanical deflections, which in turn reduces optical distortion. [4] Unlike the applications described above, which are two-dimensional, the whippletrees in telescope mirror support cells are three-dimensional designs, [ 5 ] since the tree must support multiple points over an ...
What it is: A cricket is a single roller placed within the port of a curb bit. usually containing copper, often producing a rattling or "cricket-like" sound when the horse moves it around. The cherry roller bit has multiple rollers along its mouthpiece and may be of steel, copper, or alternate between the two.
Here are some of the best photos and video from the first Saturday in May. On display was a Kentucky tradition, reflecting the grand spectacle the Kentucky Derby has become since it was first ran ...
A spade bit A poster illustrating the process of training a spade bit horse. The spade bit is a historic vaquero design for a type of curb bit with straight, highly decorated shanks and a mouthpiece that includes a straight bar, a narrow port with a cricket, and a "spoon," a flat, partly rounded plate affixed above the port, supported by braces on either side.
