- Difference between Stiffness (K) and Modulus of Elasticity (E)?
Stiffness (F=Kx) is the extent to which an object resists deformation in response to an applied force Elastic Modulus (E=Stress Strain) is a quantity that measures an object or substance's resista
- Can someone help explain the difference between strength and stiffness?
As far as I can understand, strength is a materials resistance to permanent fracture while stiffness would be resistance to temporary fracture If possible could I also get a brief explanation of ductility and resistance to fracture, and the differences between all of these I'm familiar with chemistry but new to engineering
- Why is the beam bending stiffness taken as $EI L$?
In moment distribution method, the bending stiffness of a beam is taken as EI L E I L But in these kinds of stiffness tables, the flexural rigidity is usually divided by some power of L L: So why is EI E I divided by simply L L to get the bending stiffness, instead of some of its powers as in the tables? Could somebody provide a quick derivation? Thank you!
- Whats the difference between ductility and stiffness?
Materials are usually put into a basket of either being ductile or brittle Brittle materials usually don't experience plastic deformation whilst ductile materials do Some materials might then be described as more ductile than others based on some measures and stress conditions like you described Stiffness is a global phenomenon, and it's a measure of how much deformation (could be non
- How does width and thickness affect the stiffness of steel plate?
Would making it wider help to support the weight and increase its stiffness, or do I need to make it thicker? Also is there a way to calculate how the stiffness will change with the thickness (or width if that would affect it)?
- What is the difference between Hookes Law and Youngs Modulus?
In the elastic region where stress is proportional to strain up to elastic limit which is we call Young's Modulus (E) My question is if that is E, then what is Hooke's Law (K=F x spring stiffness)
- Strength vs. Hardness vs. Toughness - Engineering Stack Exchange
for this question: "What is the difference between strength, hardness and toughness in materials?" i have searched and have found these following definitions Strength refers to resistance to
- How does stiffness rigidity affect the bending moment of a beam
The bending moment is independent of the geometry of beam, however the curvature and vertical deflection are inversely proportional to second area of moment, how thicker how bigger the latter one
