The Basics of Mechanical Engineering Course code: OSM 001124 | 6 ECTS credits

Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 1
Semester: 2
Requirements: Mathematics and physics on a high school level.
Goal: The goal is for students to obtain basic knowledge of mechanics, strength, materials and mechanical elements. Within this course, the students are introduced to the basic analysis of planar lever mechanisms, the system of strength transfer and rotational motion in textile machinery.
Outcome: The students are able to understand how machines function. They are trained to perform basic calculations for mechanical parts.

Practical instruction (Problem solving sessions/Lab work/Practical training):
  1. Using technical drawing tools. Execution of graphic work in technical drawings and descriptive geometry: construction of regular polygons, conical intersections, contours; projections of points; projections and traces of lines; plane traces and special lines in a plane; rotation of a body; oblique projection; orthogonal projections; intersection of a pyramid and a plane; intersection of two cilinders; intersection of two bodies; developing a complex surface; dimensioning and intersections. Execution of graphic work in the kinematics of mechanisms: synthesis of a planar mechanism; drawing 12 positions for the planar mechanism; constructing a hodograph of vectorial velocities for mechanism joint points; drawing a diagram of the velocity of joint points of a planar mechanism. Calculating the parameters of complex mechanical gear trains.
