#### In programs

TIMAL MECHANICAL ENGINEERING, Year 1 (compulsory)

#### Examiner:

Univ lektor  Peter Bövik

#### Eligibility:

In order to be eligible for a first cycle course the applicant needs to fulfil the general and specific entry requirements of the programme(s) that has the course included in the study programme.

#### Course specific prerequisites

Courses in Linear algebra, Calculus and Mechanics.

#### Aim

The course in strenght of materials is aming towards an understanding of the basic knowledge of stresses and deformations in constructions in order to be able to perform engineering calculations.

#### Learning outcomes (after completion of the course the student should be able to)

* Explain the difference of normal and shear stresses and strains.
* Solving problems of plane trusses both isostatic and hyperstatic systems by using a matrixmethod of displacement.
* Analyze problems in torsions of bars.
* Calculate center of mass, linear and quadratic area moment of inertia for plane surfaces.
* Calculate stresses and deformations in beams loaded in a plane.
* Solve the differential equation describing the deflection of beams in simple geometries.
* Use tables of elementary cases in deflection of beams.
* Understand the meaning of plane stress analysis and the use of principal stresses and effective stresses.
* Formulate the mathematical model by using equilibrium-, compatibility- and constitutive relations.
* Use Matlab in solving numerically a problem in strength of materials.

#### Content

The classical load cases tension, torsion and bending are treated with emphasis on hyperstatic problems. Further we treat Euler-Bernoulli theory for bending of beams and some elementary analysis of plane stress including principal stresses and effective stresses. A project task is included in the course where the student will analyse and perform numerical calculations using Matlab of an engineering task in strenght of materials.

#### Organisation

The course contains of 28 h theory based lectures and 28 h problem solving lectures and 144 h home work

#### Literature

Tore Dahlberg, Teknisk hållfasthetslära, Studentlitteratur, (2001)

#### Examination

Paper examintation containing 5 excercises with grades: not passed, 3, 4, 5 and approved project task.
