CIE 525 Lecture Notes - Lecture 2: United States Customary Units, Parallelogram Law, Unit Vector
Document Summary
Units of measurements si and us customary. Resolution of a vector using cartesian vector notation (cvn) Introduction to mechanics: rigid bodies, statics and dynamics, deformations are considered in strength of materials. Mass inertia of a body/ response to velocity. Time principles of statics are time-independent. Force action of one body on another => f=m a. Concentrated forces effect of a loading. Newton"s three laws of motion : first law. 3 of 44: between any two objects that have mass, there exists an attractive gravitational force acting on each object separately, these two forces have the same magnitude but are in opposite directions, gravitational attraction between two particles. Where the universal constant of gravitation, g, = 66. 73(10-12) m3/(kg s2) Units of measurements: three defined units or base units. 4 of 44: related by the derived unit. Force => f=m a: this course will used two systems of units. W = m g =>n = kg 9. 81m/s2: u. s. customary units.
