The method consists in (i) releasing constraints until the system is statically determinate (basic system (BS)) and (ii) introducing redundant variables (RV) corresponding to each released constraint. (Ref: Chapter 10) For determinate structures, the force method allows us to find internal forces (using equilibrium i. Mohr was an enthusiast for graphical tools and developed a method for visually representing stress.

Seismic braces can be flexible using aircraft quality cables, or rigid (solid) using steel sections such as pipe, angles, or strut channels. Braces are typi-cally installed 30-40 ft (10-13 m) apart, at system turns and at the end of runs. Suspended systems such as piping, equipment and ductwork need seis-mic braces to keep them from swaying during an earthquake. Our strong legacy includes OSHPD OPA and OPM approvals, Structural Engineer approvals, and compliance with Internation-al Building.

In literature from ancient Rome there are complaints of foul air, while in 1273 the inhabitants of London were discussing the prohibition of coal burning to improve air quality. However, the measurement and analysis of aerosols only became established in the second half of the 19th century. In 1847 presented the first concept of particles in the air in his condensation nuclei experiment and his ideas were confirmed in later experiments by Coulier in 1875.
