What causes an object to slide down a hill? Gravity, as we all know. How fast does it slide down the hill? That is determined by two things: the slope of the hill and how hard the object "pushes" against the hill. The force of gravity is always directed straight down, toward the ...
The normal force is the force that tries to push objects apart when they are in contact with each other. This is what keeps us sitting in a chair, rather than sinking through the chair as our atoms move between the atoms of the chair....
Thus, investigation of the effect of this distribution on the factor of safety is of practical significance. A series of normal stress distributions are represented by a cubic spline function with five discrete points, and the associated factors of safety are computed according to the force and ...
The work done by a force is the product of the magnitude of the force and the displacement of the point of application of the force in the direction of the force itself. In other words, the work (W) done by a force exerted on an object is the ...
(S) and the normal displacement (v) are independent of a given stress path (i.e. either CNL or CNS stress path) and are functions of the shear displacement (u) and normal force (N) not of the stiffness; in other words, the shear force S=Sˆ(u,N) and normal displacement v=v...
the linear lift slope range, and (iii) the model's roll and yaw angles are close to zero degrees. Therefore, in order to limit the scope of the current paper, the author decided to focus his investigations on a description of the use envelope of the normal force as the normal force of...
The stress is equal to the force divided by the area. On a real or imaginary plane through a rock, there can be normal force (ΔN) and shear force (ΔS), as shown in Fig. 1.1. The forces induce normal and shear stresses in the rock. It should be noted that a solid can sustain...
