simple answer is force vs mass. material strengths consider the relationship between stress and deflection. there are many different material strengths that can be considered in the design process; such as load strength, fatigue strength, yield strength, etc. we see failure when the stress on the component is greater than the material strength. force in this case is mass (kg) * gravity (m/s^2). the newton unit is (kg*m)/(s^2); so kN/(mm^2) is the stress, which is the force due to the weight (m*g) over an area. this can be confusing as the units of force in the English system is in lbf while the mass unit is lbm; but both are commonly just called pounds. hope this helps.
Thank you for watching and for your kind words! I'm glad you found the class helpful. If you have any additional questions or would like to learn more about reinforcement in concrete or other structural engineering topics, feel free to reach out. I'm always happy to help out and share my knowledge. Thank you again for your support and I hope you have a great day!
Very well explained! Concepts cleared. Thankyou
Keep making more videos on structural engineering.
I will try my best
You made my future. Thank u buddy
Great video! Full of important information thanks for sharing!
Excellently explained
That child is very well spoken
Thank you for sharing keep up the good work
Well explained! Thanks
Very Thorough. Really liked the Artistic Renderings in This Video. They brought Everything to Life for Me.
Have a Great Day.
Thank you very much for your kind words. Have a wonderful day.
thank you :)
Thanks I leaned a lot
Wright Time to watch Wright vi🤣👨🏫👨🏫🧑⚖️
Good
Excellent explanation 🎉
why do we use KN/m^2 instead of Kg/m^2 or tonn/m^2 ,Can someone give me a resonable answer ?

force in this case is mass (kg) * gravity (m/s^2). the newton unit is (kg*m)/(s^2); so kN/(mm^2) is the stress, which is the force due to the weight (m*g) over an area.
this can be confusing as the units of force in the English system is in lbf while the mass unit is lbm; but both are commonly just called pounds. hope this helps.
