86 views2 pages

Document Summary

Objectives: define mechanics and statics, understanding newton"s three laws of motion, work with two types of units, develop procedure. Fluid: very lose and not stiff; can be compressible and incompressible. Statics: deals with the equilibrium of bodies that are at rest of moving with constant velocity: dynamics: deals with bodies in accelerated motion, type of loads encountered in mechanics include self weight, vehicles, people, wind, waves, seismic activity. If the applied forces on an object is on the same point it can be idealized as a particle. Forces are concurrent considered in analysis of applied forces. For every action on one body on another there an equal and opposite reaction. Length: defines position of a point in space and thereby describe the size of a physical system: time: measure of the succession of events, mass: measure of inertia of a body. Force: push or pull exerted by one body on another; a vector quantity.
