Statics - The study of objects at rest Newton's 3rd Law - For every action force, there is an equal and opposite reaction force Vector Quantities - Physical quantity that has both magnitude and direction Force - Pushing of pulling interaction of objects Centroid - Object's center of gravity or center of mass What does a moment equal? - Force x Distance Static Determinacy - A static determinate structure is a structure that can mathematically be solved Element - Consisting of only one type of atom Metalloid - of or being a nonmetallic element that has some of the properties of metal Manufacturing Process - A series of operations that transform raw or unfinished materials into finished products Linked-Cell Shop - Manufacturing connected to final assembly; lean production system; one piece flow system Project Shop - Product being manufactured cannot be easily moved during production; production processes are brought to the productLean Manufacturing - 100% good units flow from process to process Integrated Quality Control (IQC) - All employees are also inspectors Forming and Metalworking - Molding shape, size, and physical properties of a material Rolling - Material passes through series of rollers which reduces thickness Forging - shaping metal by heating and hammering Elastic Limit - Maximum stress that a material will withstand without permanent deformation. Resilience - the physical property of a material that can return to its original shape or position after deformation that does not exceed its elastic limit Yield Point - point at which deformation becomes permanent Plastic Deformation - Unrecoverable elongation beyond elastic limit Toughness - Shows both strength and ductillity; total area under stress-strain curve from test initiation to fracture Probability - a measure of how likely it is that some event will occur Experimental Probability - probability based on the repeated trials of an experiment Theoretical Probability - the ratio of the number of favorable outcomes to the number of possible outcomesExperiment - Activity with observable results Event (Probability) - Subset of sample space Sample Space (Probability) - Set of all possible outcomes
