Strength of Materials also known as Mechanics of Materials or Solid Mechanics or Mechanics of deformable bodies. In this subject we study the internal resisting forces developed inside the body which causes deformation in the body. By analyzing this deformation one can obtain the various unknowns such as strength (also known as stress ) strain, young's modulus and various other mechanical properties which will be discussed later. Here we study the load withstanding capacity of the body to the externally applied forces .The strength of the material is its ability to withstand applied load without failure.
In this subject we study the following topics which help the students to solve their semester exams and GATE problems.
Simple stresses , strains and Thermal stresses
Compound stresses or Principal Stresses
Theories of Failure
Thin and thick cylinders
Shear Force and Bending Moment diagrams
Stresses in beams
Slope and deflection of beams.
Torsion of circular shafts
Buckling of columns
Study of the above topics helps the students to solve GATE problems. Mechanical GATE syllabus also shown here.
