Show hintHide hint
Think about the three dimensions in cylindrical space.
Question 2.
Explain what happens to e_r as θ increases.
Show hintHide hint
Consider the motion around a central axis.
3Question 3.
What are the basis vectors in cylindrical coordinates?
- e_r
- e_θ
- e_z
- e_x
- e_y
- e_z
- r
- θ
- z
Show hintHide hint
Visualize each coordinate and its direction.
4Question 4.
True or False: The radial vector e_r remains the same as θ changes.
- True
- False
Show hintHide hint
Recall how e_r behaves in motion.
Question 5.
A mass is moving in circular motion with the radius defined by e_r. If θ changes rapidly, analyze the implications on the mass’s linear momentum.
Show hintHide hint
Focus on how the rapid change in θ impacts the forces on the mass.
Question 6.
Given that e_θ rotates with θ changes, calculate how the rotational velocity affects the resultant force in a cylindrical coordinate system.
Show hintHide hint
Apply the principles of rotational motion and how they interrelate with e_θ.
