Working a muscle against an immovable object; tension is developed but no mechanical work is performed; contraction of a muscle in which shortening or lengthening is prevented; involves muscular force equal to, but not greater than the resistance.
Isometric describes the contraction of muscles when the fibers increase in tension, but do not shorten in length. Isometric exercises can be induced in muscles that are used when a limb is made to pull or push against something that does not move.
Also called the cubic crystal system. Crystals can form in the shape of a cube (like halite and pyrite), an octahedron (diamond), dodecahedron (garnet), trapezohedron (garnet), and others. The most common and recognizable in this class are the cube, the octahedron, and the dodecahedron. Isometric crystals have three axes of symmetry, all at right angles to each other, and all of the same length. Examples: pyrite, halite, garnet
Games are called isometric when their world maps are based on grids of tiles which are drawn to the screen without taking perspective into account (orthogonal). The game view is necessarily top-down in such games.
non-perspective means of constructing a three dimensional view based on orthographic information. An isometric view employs vertical lines and receding axes at 30 degree angles from the horizontal, all ellipses are 35 degrees.
