Statics
FSI-3ST-A Acad. year: 2025/2026 Winter semester
Introduction to solid mechanics and Statics, its relation to other courses of solid mechanics. Model and theoretical aspects of engineering mechanics, specification of basic terms and general principles. Introduction to and discussion of the elements of Statics – force, moment of force about a point, moment of force about an axis. Classification of force systems and their resultants. Equivalent force systems. Replacement of a force system by a force and a couple, replacement of a force system by a single force. Conditions for rigid-body equilibrium. Basic tasks of Statics. Centre of gravity and methods of its evaluation. Body supports and connections, their computational models, kinematic pairs. Degrees of freedom of a single body, constraints, concept of a free-body diagram. Statically determinate and indeterminate problems. Algorithm of static equilibrium solution of a body and its application to the analysis and solution of statically determinate systems, mechanisms and trusses. Basic graphical constructions. Passive resistances – their analysis and computational models, dry friction and rolling resistance. Free-body diagrams in actual states of motion. Application to engineering problems including friction forces and rolling resistances. Integral and differential approach to calculation of the resulting internal forces and moments in straight rods.
