Academic Year 2013/2014

  • Teaching Mode: In-person learning (entirely or partially)
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Mechanical Engineering (cod. 0927)

Learning outcomes

The student acquires and consolidates the basic concepts of general physics in the mathematical analysis and vector and integral calculus language. Also acquires the scientific-technical methodology required to deal with the problems of physics, with regard to classical thermodynamics and electromagnetism.

Course contents

Thermodynamics systems. The zero-principle of  thermodynamics. Temperature and thermometers. thermodynamic transformations and changes in the state. Adiabatic work, internal energy and first principle of thermodynamics.  Heat , work and  conservation of energy in a general sense. Thermal capacity, heat molars, specific and latent. The ideal    gas : state equation , internal energy, Poisson equations. The second principle of thermodynamics. Reverisibility  and irreversibility. Thermal cyclical machines and their performance. The second principle of thermodynamics. Cycle and theorem of Carnot. Temperature's  absolute scale . Clausius's theorem and  entropy. Law of growth of entropy.

Electricity. Coulomb's law, electric field and electric potential, Gauss's law for the electric field.. Electric  dipole . Theorem of divergence and theorem of Stokes. Motion of electric charges  under the presence of  electric  fields. Electric current, continuity  equation for the electric current. Magnetic forces and their property. First and second equation of Laplace. Gauss law for the magnetic field. Ampère-Maxwell law. Faraday-Lenz law. Electromagnetism :  the equations of Maxwell. Wave phenomena. Outline on electromagnetic waves. Energy aspects of the electromagnetic field. The  Poynting theorem.

Further information .- The course demands that the student become familiar with the indispensable elements of mathematical analysis and calculus, such as multiple integrations.

Teaching methods

The course will take place during the second semester and it represents the second part of the integrated course of Fisica Generale T.C.I.  for an amount of 12 cfu ( course credits ). The first module, Fisica Generale T-A,  will take place in the first semester. Each of the two courses is of 6 cfu. The course of Fisica Generale T-B  is organized in frontal lessons in classroom where first of all the theoretical aspects of the treated arguments are introduced. In particular  the basic notions, the main theorems and results in the fields of  classic thermo-dynamics and electro-magnetism will be enunciated and in some cases demonstrated. Later on the wave phenomena will be introduced and in detail the electro-magnetic waves will be treated. Then some time will be dedicated to the application of the notions introduced and to the resolution of the exercises.

Assessment methods

The examination consists of a final two hours written test and of a further oral exam. During the written examination books, notes and computers are forbidden. The written examination includes the resolution of numerical exercises, each with one or two independent questions, and the resolution of a same number of essentially theoretical questions with open answers.  In order to accede to the oral examination, one must have reached a minimum threshold in the written exam and in this case the grade obtained remain valid for one year . The oral examination starts from a close look of the written one and  aims to  verify the student's basic knowledge and the understanding of the several theoretical aspects of the discipline acquired during the course. The final mark is calculated as the arithmetic average of the written and oral examination marks.
