ENGINEERING MECHANICS Forces and moments: concentrated force, moment of a force about a point, addition of forces, rigid body equilibrium. Statically determinate beams and framed structures: geometrical stability, reactions, internal forces (normal-force, shear-force and bending –moment diagrams). Concepts of stress and strain: deformable body, normal stress and strain in axially loaded bar, stress and strain components in an infinitesimal orthogonal element of the body. Mechanical properties of a deformable body: stress-strain diagram, brittle and ductile behavior, Hooke law, Poisson ratio, shearing stress-shearing strain diagram. Torsion: shearing stresses and deformation in structural members with circular and rectangular cross sections in the elastic and inelastic range. Bending: simple and skew bending of structural members with symmetrical cross section, bending of structural members made of several materials deflection of beams, statically indeterminate elastic beam problems. Shearing stresses in structural members: shearing stresses in structural member with symmetrical cross section, shearing stresses in thin-walled members. Combined stresses in structural members: stresses from combined action of bending, transverse and axial loadings, transformation of plane stress, principal stresses, Mohr circle. Buckling of column: the Euler formula for a pin-ended column, elastic buckling of column with different end restraints. Laboratory tests: tensile and compressive tests for ductile and brittle materials, determination of elasticity modulus, torsion test.
