Support and Connection Types - MIT
The knee can be idealized as a connection which allows rotation in only one direction and provides resistance to lateral movement. 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
Physics Tutorial: Closed-End Air Columns
Many musical instruments consist of an air column enclosed inside of a hollow metal tube. If an end of the tube is uncovered such that the air at the end of the tube can freely vibrate when the sound wave reaches it, then the end is referred to as an open end. An instrument consisting of a closed-end air column typically contains a metal tube in which one of the ends is covered and not open to
Effect of soil reinforcement on rocking isolation
Dec 01, 2018· The Inclusion of rocking motions in the foundation in structural analysis is a new approach in seismic designs that can reduce the column-base moments and transfer the plastic hinge(s) to the soil.
