Chapter 2 Flashcards
1
Q
What are axially loaded members?
A
Structural components subjected to tension or compression.
2
Q
What does it mean for a material to be linearly elastic?
A
This means that load and elongation is proportional. That is, behavior follows Hooke’s law.
3
Q
How are stress and strain related?
A
By young’s modulus E
σ = Eε
4
Q
What is axial rigidity?
A
The product of E and A
5
Q
What is stiffness?
A
Stiffness is the force required to produce a unit elongation, or P/δ. Denoted by k
6
Q
What is flexibility?
A
Flexibility is the elongation due to a unit load, or δ/P.
Denoted by f
7
Q
What does k equal?
A
= EA / L
8
Q
What does f equal?
A
= L / EA
9
Q
What is the effective area of a cable?
A
The effective area of a cable is the total cross - sectional area of the individual wires that make up the cable.
