4 cards from this section. Quick, good the night before a test.
What is static equilibrium?
Think about the principles of motion.
Name the two primary stress components in a hollow cylinder.
Consider the directions these stresses act.
What defines static equilibrium in mechanics?
Consider forces and their points of application.
True or False: Boundary conditions have no effect on the solutions to stress equations.
Think about how we calculate stress at surfaces.
Given a hollow cylinder with an internal radius of 2 cm and an external radius of 4 cm subjected to a pressure of 200kPa, derive the expressions for radial and hoop stresses.
What are the applicable equations for equilibrium of forces?
Analyze how the stress distribution changes if the cylinder's material is altered to a less ductile one while maintaining the same geometry and internal pressure.
Think about how material behavior changes the way stress is distributed.
