A FALLING BODY MACHINE

A simple body weighing machine.

It is customary to weigh the organs removed at necropsy and these measurements provide objective criteria of atrophy, hypertrophy, and disease. However, surprisingly few mortuaries have facilities for weighing whole bodies. When this hospital opened in 1970 attempts to obtain a body weighing machine within the limits of the budget were unsuccessful and a simple modification of the body elevatin...

A Falling, Folded String

This classic problem was brought to the author’s attention by Johann Otto. This view seems to be advocated by Routh (1896) in Ex. 4, p. 82 of [13]. Examples of falling chains were often considered at Cambridge U. [11, 12, 13, 14, 16, 18, 19], as recounted in a footnote on p. 80 of [13]: Problems on infinitesimal impulses were solved in the lecture room of the late Mr Hopkins as long ago as 1850...

Application Of Extended Kalman Filter For A Free Falling Body Towards Earth

State estimation theory is one of the best mathematical approaches to analyze variants in the states of the system or process. The state of the system is defined by a set of variables that provide a complete representation of the internal condition at any given instant of time. Filtering of Random processes is referred to as Estimation, and is a well-defined statistical technique. There are two...
