Yes YES!! Thank you for these. I'm such a bad notetaker :/ will definitely be looking forward to these

What is structural dynamics?We also discuss several other topics like Give an example of infinite integral.

Why is it paired with aeroelasticity?If you want to learn more check out economists reason that the optimal decision is to continue

If you want to learn more check out How do you determine thermodynamic state?

This course:

Don't forget about the age old question of zoleman

We also discuss several other topics like What are variables that can only assume whole numbers?

Don't forget about the age old question of Where did the term horsepower come from?

Structural Dynamics

  • Rigid body dynamics → object of interest doesn’t flex
  • Aeroelasticity takes into account flex, rotation, twit under loads
  • Continuous system →  simplify structure: wing becomes a linearized problem like a beam/string
  • Material is the same across structure → homogeneous
  • Isotopic →  mass is constant
  • Follow Hooke’s Law: stress and strain are linearly proportional in elastic region of material
  • Solving linear problem: small deflections
  • Problem can have ∞ degrees of freedom → continuous system with →  points

→ truncate to “n” DOF (dof)

Equation of Motion:String

  • String attached at both ends

→ making sound waves and describing motion of string to get sound wanted

Assumptions:

→         • string is elastic

• forces due to tension (bonding negligible)

• continuous: differential element

                                                                        (mass per unit

length)

                                                                              Equilibrium position

After disturbance                                                        equilibrium position

Looking at ds:

M =  (same as or l)

T = tension, not necessarily same across string

* for small deflections 2nd and order terms are negligible

* with small deflection assumption, problem becomes linear

  • To find : tan=        ∴
  • Newton's 2nd law:  → there will be accelerations in the given coordinate directions
  •  dof but only two coordinate directions so need 2 equation of motion to solve
