Cant itself refers to the superelevation of the curve, that is, the difference between the elevations of the outside and inside rails. Cant deficiency is present when a rail vehicle's speed on the curve is greater than the speed at which the components of wheel to rail force are normal to the plane of the track.
The weight may be gradually increased up to 50% of the body weight, which would permit the affected person to stand with his body weight evenly supported by both feet (but not to walk). Weight-bearing as tolerated: Usually assigned to people that can support from 50 to 100% of the body weight on the affected leg, the affected person ...
Cant gradient is the amount by which cant is increased or decreased in a given length of track. The change in cant is required in order to connect a tangent track (no cant) to a curved track (with cant) through a transition curve. The rate of change of cant is used to determine the suitable cant gradient for a given design speed.
The stiffer hoof reduces the foot's load attenuation capacity, rendering the horse unable to bear much weight on the distal limb. Similar characteristic features emerge in the human foot in the form of the pes cavus alignment deformity, which is produced by tight connective tissue structures and joint congruency that create a rigid foot complex.
En pointe dancers employ pointe technique to determine foot placement and body alignment. When exhibiting proper technique, a dancer's en pointe foot is placed so that the instep is fully stretched with toes perpendicular to the floor, and the pointe shoe's platform (the flattened tip of the toe box) is square to the floor, so that a substantial part of its surface is contacting the floor.
The primary advantages of a plantigrade foot are stability and weight-bearing ability; plantigrade feet have the largest surface area. The primary disadvantage of a plantigrade foot is speed. With more bones and joints in the foot, the leg is both shorter and heavier at the far end, which makes it difficult to move rapidly.
Fistmele - the measure of a clenched hand with the thumb extended; Gradus - Ancient Roman step; Hand - breadth of a human hand; Klafter - German measure of outstretched hands; League - the distance a person can walk in an hour (by one definition) Orgyia - Ancient Greek fathom; Parasang - the distance an infantryman could march in a predefined ...
The ground pressure of motorized vehicles is often compared with the ground pressure of a human foot, which can be 60 – 80 kPa while walking or as much as 13 MPa for a person in spike heels. [ 3 ] Increasing the size of the contact area on the ground (the footprint ) in relation to the weight decreases the unit ground pressure.
