**Update Mar 2**The last problem (Tongue 4.38) is for**extra credit**

**Update Mar 3**Typo: the coupling spring in**Problem 3**is torsional, so its units should be Nm/rad. In**Problem 1**, assume the beam is of negligible stiffness.**Homework 7**

**Update Feb 1**In Problem 3, L_eq = H/2. Notation updated to unambiguous form - 1/s means rad/s, not Hz.

**Update Feb 2**In Problem 3, a typo was corrected: the text should refer to "zeta" as damping RATIO, not as damping coefficient.**Homework 3**

Answers to FAQ: In problem 3, you can treat the slider as a point-mass.

Damped frequency is defined only for underdamped systems, since for overdamped systems there are no oscillations in the output.**Homework 2**

Jan 8:**Problem 2 update**: Unstretched rope length L = 0.4 m

Jan 12:**Problem 2 update**: You can assume that the rope stays horizontal during the motion.

Jan 13:**Problem 2 update**: Use t_final = 3 in your simulation.

Jan 13:**Problem 3 update**: Typo, instead M_eff it should read M=200 kg, i.e., the total mass of the cantilever is specified. The oscillating mass is then 200/3 kg.

Solutions to the Midterm 2

**Note:** You are allowed to have TWO sheets of handwritten notes as a reminder during the final.

The Sections in the book we covered so far:

- Chapter 1- all except 1.5
- Chapter 2 - all
- Chapter 3 - all

In addition, we covered laplace transform method that is not covered in the book. The Midterm covers material **up to** **lecture 12** in lecture notes.
