A body is said to be "free" when it is singled out from other bodies for the purposes of dynamic or static analysis. The object does not have to be "free" in the sense of being unforced, and it may or may not be in a state of equilibrium; rather, it is not fixed in place and is thus "free" to move in response to forces and torques it may experience.

Hertz solved the contact problem in the absence of friction, for a simple geometry (curved surfaces with constant radii of curvature). Carter considered the rolling contact between a cylinder and a plane, as described above. A complete analytical solution is provided for the tangential traction.
The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.
A hacker gained access to an online secure document-sharing file between attorneys involved in a civil lawsuit brought by a close friend of former Rep. Matt Gaetz, according to sources familiar ...
From January 2008 to December 2012, if you bought shares in companies when Richard B. Myers joined the board, and sold them when he left, you would have a 4.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
Martin Gardner presents and discusses the problem [1] in his book of mathematical puzzles published in 1979 and cites references to it as early as 1895. The crossed ladders problem may appear in various forms, with variations in name, using various lengths and heights, or requesting unusual solutions such as cases where all values are integers.
From January 2008 to December 2012, if you bought shares in companies when Charles K. Gifford joined the board, and sold them when he left, you would have a -72.0 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
