Abstract:
This course provides students with practical experience in testing and calculating of mechanical properties of materials.
Using various measurement equipment, the students apply topics learned in Material Science courses 1&2, and Strength of materials
1 about responses of materials to different types of mechanical loading and heat-treatments.
The students acquire knowledge of operating standard engineering
measurement equipment and deepen their understanding of material properties.Abstract:
This course is designed to provide students with concepts in measuring systems, transducers and measuring devices, data logging systems, calibrations, thermal experiments, environmental conditions experiments.Abstract:
The course covers the basic topics of mechanical design,
an analysis of power transmission by a variety of methods, related parameters, initializing with friction transmission and mechanics laws for moments transmission, through design of forces and stresses by Hertz's equations, design of most kinds of belts power transmission and other friction transmitting machines.
A thorough course is included to understand and enable design of gears, spur gears, bevel gears, worm gears, including analysis of forces and moments, design stresses, evaluation of surface contact stresses to predict gears life and design for fatigue. Planetary systems are explained and designed.
A self-sustained chapter of spring design is incorporated.
Chain transmissions are dealt, design and use of manufacturer's
catalogs are explained, the student acquires abilities of design of different types of chain transmissions.
Another chapter deals with lifting and hoisting elements such as
chains, slings, steel cables, hooks, drums and rollers for cables, design for maximum loads and durability
During the course students perform project in mechanical design field with a presentation.
