Q$1(10$ pts$)$: The angular frequency of an oscillator always looks like a ratio of "something" over "something

else". What is this conceptual pattern you can use to quickly get the angular frequency of a system?

$\backslash$omega $^(2)=$

Q$2(10$ pts$)$: If you ever need to compute torques for an object that is accelerating, you should always

compute the torques about an axis going through which point? Circle one.

A$.$ The point about which the object is actually rotating.

B$.$ The contact point between the object and the floor.

C$.$ The center of mass.

D$.$ The point at which an external force is being applied.

Q$3(80$ points$).$ In the figure at right, the monkey's weight is W$=90$N$.$

The bar has a weight W$\_($B$)=240$N$,$ and is $3$ m long. The whole system

is stationary, and the bar is perfectly horizontal. Find the tension in each

of the two strings, and find the angle $\backslash$theta $.$ As usual, derivations with

numbers instead of variables are worth no points.
