    Mar 31, 2020· Stable atoms retain their form indefinitely, while unstable atoms undergo radioactive decay. Most naturally occurring atoms are stable and do not decay. The nucleus of an atom is made up of protons and neutrons. The forces inside the nucleus of a stable atom are balanced because the nucleus contains the proper number of protons and neutrons.

  • Support and Connection Types - MIT

    The design of a pinned connection is a good example of the idealization of the reality. A single pinned connection is usually not sufficient to make a structure stable. Another support must be provided at some point to prevent rotation of the structure. The representation of a pinned support includes both horizontal and vertical forces.

  • Crystal structure - Wikipedia

    Unit cell. Crystal structure is described in terms of the geometry of arrangement of particles in the unit cell. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α
