- 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 $EI L$ But in these kinds of stiffness tables, the flexural rigidity is usually divided by some power of $L$:
- 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
- mechanical engineering - What is the difference between torsional . . .
Torsional stiffness is the rigidity of one unit length of the bar It is derived by dividing the torsional rigidity by the length L In the case of two shafts with the same torsional stiffness but one is twice as long as the other and both are exposed to the same torque, the longer shaft twists twice
- civil engineering - Definition of stiffness for structural dynamics . . .
The definition of stiffness as I know it is: k = F d ie the stiffness of a structure in a direction is proportional to the Force applied to the location divided by the deflection of the structure at that location due to that force However in the case of these structures, the stiffness will vary depending on the direction I apply the load
- structural engineering - Elasticity values in stiffness matrix . . .
Can’t you approach the calculation of any behavior of a material from the elasticity approach or the stiffness approach? Then what goes in the matrix is relevant
- Parallel vs series springs - Engineering Stack Exchange
I am trying to understand how to simplify a mechanical system of multiple springs where their ends are fixed In this example, kA and kB are effectively in parallel: Is equal to: And so we can co
