Introduction

An architect has to handle many variables to design a building, this is the main reason why the grade of architecture is so versatile and is articulated in different branches.

Generally speaking, we could say that Physics is divided into three parts: Classical Physics, Modern Physics and Contemporary Physics.

Inside of Classical Physics, among other branches, we found the Classical Mechanics, Sound and Optics, which are the three parts into which the subject of Physics of the first course of architecture is divided.

        1. CLASSICAL MECHANICS.

It is the branch of Classical Physics that studies the behaviour of bodies under the action of a system of forces.

Given the breadth of this branch, is usual to divide the study of Classical Physics in three parts: Mechanics of Rigid Bodies, Fluids Mechanics and Mechanics of Deformable Bodies.

The subject of Physics introduces to the student into the Mechanics of Rigid Bodies and into the Fluid Mechanics. The Mechanics of Deformable Bodies is taught in the second course of the grade.

It is noteworthy that the Mechanics of Rigid Bodies is divided into two main sections:

Static: Study the bodies submitted to equilibrated forces, that is, bodies at rest or in uniform motion.
Dynamics: Study the motion of the bodies, essentially their trajectory versus time, (Kinematics), and study the bodies under non uniform motion, that is, under accelerated motion, (Kinetics).

Static is the theory usually taken in the first course of the grade of architecture, since so many practical structural problems of edification can be analyzed by applying its principles.

The introduction to the main concepts of Static is fundamental to learn correctly the structures subjects that are imparted in superior courses.

 

2. HEAT TRANSFER

 

It is the branch of physics that studies thermodynamics. The heat transfer is the process of thermal exchange between different parts.

 

This concept is particularly important in order to determine the heat and cooling loads, facade, ventilation and thermal comfort. This allows calculating and reducing energy consumption of the building.


        3. SOUND

It is the branch of Classical Physics that analyzes the sound vibrations. The study of acoustics involves the way that the sound waves travel through specific means.

The quality of one project may be affected if the building do not have a good acoustic, especially in some edification typologies, and is therefore important for an architect to know the main concepts of the sound.

        4. OPTICS

It is the branch of Classical Physics that explores the properties of light since the visible spectrum to ultraviolet and infrared radiation.

Lighting can be a key factor to design a building, so it is reasonable to know the principles of optics.

Pre-course requirements

It is recommendable:

To know the main concepts that are taught in high school.
Pass the Mathematics subject that is taught in the first semester of the first course of architecture.

Teaching and learning activities

In blended



The methodology and training activities are presented as a hybrid system (virtual and face-to-face). In this way, if the situation requires it, both student and teacher will be prepared to move to a fully face-to-face or totally virtual scenary, without any loss of time.

Classes will take place on Tuesdays and Wednesdays from 15:00 a.m. to 18:00 p.m.

Tuesday: Fully virtual. Theoretical or master classes interspersed with participatory classes in which exercises will be carried out.

On the UIC's Moodle platform (intranet), available in all subjects of the University, the student will find all the necessary resources to follow up online without having to download any program or application. Programs such as Collaborate or tools such as "Homework", among others, allow online classes and exercises to be sent back to students, privately and independently, for grading. It is also feasible to carry out tests and / or multiple-choice exams to assess the student continuously.

Wednesday: Fully face-to-face. Fully practical classes will be taught. The student will have to solve proposed exercises based on what is explained virtually on Tuesdays.

The practical classes will be held in three classrooms, each with a teacher, where the students will have the appropriate safety distance. Students can upload their questions or exercises to Moodle, which will be projected on the screen for teacher supervision. In this way the doubts of the students will be solved with the appropriate safety distance through the use of "Tablets". Waxing will also be used when no exchange of information is required between teacher and student
