  1. Stepping to the world of Machines Harikrishnan C Assistant Professor Rajagiri School of Engineering and Technology Kakkanad

  2. Introduction to Mechanical Engineering • What is engineering? • What do mechanical engineers do? • The basic engineering process

  3. Engineering Job Descriptions • Analytical engineer • Design engineer • Test engineer • Manufacturing engineer • Development engineer • Research engineer • Sales engineer • Engineering manager • Consulting engineer

  4. What is Mechanical Engineering? • Broadest of all engineering disciplines. • Mechanical engineers apply the principles of mechanics and energy to the design of machines and devices: ENERGY and MOTION

  5. What will you study as an ME student? • Forces, motion, structures: statics, dynamics, kinematics, mechanics of solids and fluids. • Energy: thermodynamics, heat transfer • Materials: materials engineering & processing, manufacturing. • Machines: graphics, design, machine elements, controls. • Economics: engineering economic analysis, cost engineering. • Human and Social Studies: arts, humanities, social sciences, history, government, ethics, law. • Overall foundation: math, physics, chemistry, biology, analysis skills, communication skills, computation skills.

  7. Tacoma Narrows Bridge • The main font of the bridge near Tacoma, Washington was 28000 ft long, 39 ft wide and the steel stiffening girders (shown during construction) were 8 ft. tall.   • The bridge was open for traffic on July 1, 1940.  In four months of active life of the bridge before failure, many transverse (vertical) modes of vibration were observed before November 7, 1940.

  8. How can we design a screw which can be tightened only?

  10. WHY ARE HEXAGON NUTS & BOLTS HEXAGON?

  11. The reason they’re so popular is because the hexagon shape of the head is very versatile, it can be grabbed by tools from all angles and even by hand. • They’re easy to tighten and loosen thanks to their 6 sides, and you can access them from 360 degrees providing there’s space to move your tools.

  12. Why doesn't a bicycle move backwards when one pedals back?

  13. Thermal Engineering  • Thermodynamics • Applied Thermodynamics • Fluid mechanics. • Heat and mass transfer etc.

  14. Manufacturing engineering  • Engineering materials. • Manufacturing technology. • Manufacturing processes. • CAD/ CAM (computer aided designing/ manufacturing) etc.

  15. Design Engineering • Engineering mechanics, • Strength of materials. • Design of machine components, • Kinematics of machines, • Dynamics of machines, • Theory of machines,etc.

  16. Industrial Engineering • Operations management, • Operations research, • Total quality management, • Industrial engineering, • Project management, etc.

  17. CNC Training • CAD/CAM Training • AutoCAD • AutoCAD 2D & 3D • Pro/E • Catia • Ansys • HyperMesh Training • Safety • Boiler Operator Training • Fire & Safety Course • Piping Design Training
