Stress State: Dive into the World of Forces and Stresses!

Are you ready for an exciting journey into the world of physics? Then buckle up and discover the secrets of the stress state with us!

What is stress? Imagine you are building a giant Lego structure. The individual blocks push and pull against each other - that's exactly what stress is! In this course, you will learn how to calculate and understand these forces.

Stress components: Break down stress into its individual parts and discover how they interact. Just as a puzzle consists of many pieces, stress is also made up of different components.

Calculation: Crack the code of stress calculation! With a few clever formulas and tools, you can determine the forces in any component.

Transformation: Stresses change depending on the perspective. Learn how to transform them into different cutting planes and thus make the whole story of the load in the component visible.

Maximum stresses: Where does the greatest danger lurk? Find out where the stresses are highest in the component and how you can minimize them.

Mohr's circle of stress: This ingenious tool helps you to visualize stresses and to grasp important information at a glance.

Discover the fascination of the stress state! In this course you will not only learn dry knowledge, but also immerse yourself in the world of engineering. With good explanations and exciting application examples, the stress state becomes child's play.

Together we are strong! We will accompany you on your journey and help you to understand the complex concepts of the stress state. With our support you will master every challenge and become an expert for stable constructions.

So what are you waiting for? Start your journey into the world of stress now!

1.3 Conversion Table for Stress Units

Stress Units: Your Handy Guide for Stress-Free Conversions

Do you struggle with stress units? Numbers that scare you? Don't panic, I can help! This table is your lifesaver.

Forget complicated formulas! Here you will find all important conversions in a practical matrix. It's never been easier!

Units:
  • Pa: The hero's unit. Tiny, but mighty. (1 Pa = 1 N/m2)
  • MPa: Megapascal, the star of technical mechanics. With it, you can rock any task! (1 MPa = 1 N/mm2)
  • GPa: Gigapascal, the giant among units. Incredibly strong, but rarely used. (1 GPa = 1000 MPa)
  • N/mm2: Also called Megapascal, but a bit more shy. (1 N/mm2 = 1 MPa)
  • kN/mm2 Kilo-Newton per square millimeter. Sounds complicated, but it's easy. (1 kN/mm2 = 1000 MPa)
  • N/m2 The little brother of Pa. Not as glamorous, but useful.
  • kN/m2 Kilo-Newton per square meter. Powerful, but not used as often.
  • bar The unit from the past. Still relevant, but no longer the star. (1 bar = 0,1 MPa)
Pa MPa GPa N/mm2 kN/mm2 N/m2 kN/m2 bar
1 Pa = 10-6 10-9 10-6 10-9 1 10-3 10-5
1 MPa = 106 10-3 1 10-3 106 103 10
1 GPa = 109 103 103 1 109 106 104
1 N/mm2 = 106 1 10-3 10-3 106 103 10
1 N/m2 = 1 10-6 10-9 10-6 10-9 10-3 10-5
1 bar = 105 0,1 10-4 0,1 10-4 105 100
How to read the table:

Column 1: The unit you want to convert from.
Row 1: The unit you want to convert to.

The intersection of column and row shows the conversion factor.

Examples:
  • 1 GPa = 1000 MPa? Easy! Just read the row "1 GPa" and the column "MPa". There you have it: 1000 MPa! This also means: 1 GPa = 1000 N/mm2 = 1 kN/mm2 = 109 N/m2 = 106 kN/m2
  • 1 MPa = 1 N/mm2? No problem! Row "1 MPa" and column "N/mm²" - et voilà: 1 N/mm2! In this row you also find: 1 MPa = 106 N/m2 = 1000 kN/m2
  • 1 Pa = 0,000001 N/mm2? So small, it's almost invisible. But the table tells you: row "1 Pa" and column "N/mm2". But you can also see: 1 Pa = 1 N/m2
Tip:

Save this table as an image on your phone. So you always have it at hand when you are stressed again.

And now: Go for it! With this table, you can master any stress unit.
