Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.

In the floor plan below, the rigidities of walls A, B, and C are 1.0. The rigidity of wall D is 1.5. For a force of 100 kips in the horizontal direction, determine the maximum diaphragm shear per unit depth (absolute value). Assume that the center of mass is at the center of the diaphragm. To obtain this answer you will first need to compute the location of the center of rigidity and the force in each wall. 10' 10' A 10' CR D 10' X B
