Question 1.
What are the three components of the cylindrical coordinate system?
Show hintHide hint
Think about how you locate a point in space.
Question 2.
Define isotropic materials.
Show hintHide hint
Consider the directionality of properties.
3Question 3.
What is the relationship between stress and strain for isotropic materials?
- It depends on the coordinate system
- It is consistent regardless of the coordinate system
- It is only defined in Cartesian coordinates
Show hintHide hint
Remember the definition of isotropy.
4Question 4.
True or False: In cylindrical coordinates, the stress-strain relationship must be re-derived for every different cylinder geometry.
- True
- False
Show hintHide hint
Think about the uniformity of material properties.
Question 5.
A cylindrical pipe of radius 1m is subjected to internal pressure, resulting in a radial stress of 100kPa. Calculate the radial and circumferential strains transmitted through the material using Young's modulus of 200GPa.
Show hintHide hint
Don't forget to account for the relationship between radial and circumferential stress in your calculations.
Question 6.
Discuss the implications of anisotropic materials concerning stress-strain relations in a cylindrical coordinate system, drawing contrasts with isotropic properties.
Show hintHide hint
Analyze the inherent differences in behavior under load.
