# Mechanics 2015-2016 - BYG2251 - 10 ECTS

## Expected learning outcomes

The course provides a basic introduction to statics and strength of materials, equilibrium and elasticity.
After completion the student should be able to:

Knowledge:

• explain how basic problems concerning statics and strength of materials can be resolved
• describe what is meant by static equilibrium
• explain different support conditions
• elaborate materials elasticity and stiffness, Hooke's law, and Young's modulus

Skills:

• assemble forces to a resultant and decompose forces
• find support conditions and joint forces
• calculate normal forces, shear forces, bending moment, torsion moment
• calculate bending, normal and shear stresses, and combining these
• calculate the centroid of area, 1st and 2nd moment of area and section modulus, and be able to apply the parallel axis theorem

General competence:

• know the Euler-Bernoulli beam theory (the Engineer's beam theory)
• explain Navier hypothesis (cross sections remain planar and normal to the deformed centerline)

## Topic(s)

STATICS

• Statics basis
• Plane force systems - beams and simple frames
• Plane rod systems - Trusses
• Diagrams for normal forces, shear forces and bending moment
• 3-moment equation (basic, practical)
• Cables and ropes

STRENGTH OF MATERIALS

• Centroid of area and 2nd moment of area
• Stresses and strains (basic)
• Stresses in beams - simple cross-sections
• Torsion - circular cross sections
• Buckling

## Teaching Methods

Lectures

This course is made for students at campus in Gjøvik and also for web based students.
