3 cards from this section. Quick, good the night before a test.
Define dynamic analysis in your own words.
Think about how forces behave differently in motion than at rest.
What is the purpose of using D’Alembert’s Principle?
Recall what fictitious forces represent.
What is dynamic analysis primarily concerned with?
Think about what forces affect systems in motion.
True or False: D’Alembert’s Principle allows us to treat a dynamic system as if it were static.
Consider how dynamic problems can be simplified.
Given a slider-crank mechanism with a crank radius of 0.15m, and a piston mass of 8 kg, if the theta angle is 30 degrees and the crank rotates at 2 radians/second, calculate the piston's acceleration.
Break down the components and calculate them separately.
A four-bar linkage is under motion. If internal torques balance out at 20Nm, but external torques from a motor input 65Nm, how much torque must the system provide to maintain equilibrium?
Consider how equilibrium affects the dynamics of the system.
