2023 - 2024 Spring Semester MKT2142 Mechanics of Materials Introduction Instructor: Assoc.Prof. Umut KARAGÜZEL References Grading Quizes & Attendance: 30% Midterm Exam: 30% Final exam: 40% Class Attendance: ≥ 70% 3 Background on Statics (Pre-requisition) Engineering Mechanics I or Statics includes; ▪ Establish free body diagrams, vectors ▪ Solve equilibrium problems ▪ Internal /external forces, Reaction Forces ▪ Analyze distributed loads ▪ Structural Analysis, Diagrams ▪ Centroids, First/Second Moment of Inertia etc……… Introduction Mechanics of materials course involves both analysis and design of a given structure under load by determining stresses and deformations. The objectives of this course are: ➢To develop techniques for the quantitative analysis of the behavior of structures in tension, torsion and bending. ➢To learn some techniques to determine the stress and strain states. ➢To develop an understanding elastic buckling. ➢To obtain skill in solving problems including the analysis of statically indeterminated structures.
