Would the frequency of the angular simple harmonic motion (shm) of the balance wheel increase or decrease if the dimensions of the balance wheel were changed as described?

Yes the frequency of the angular simple harmonic motion (SHM) of the balance wheel increases three times if the dimensions of the balance wheel reduced to one-third of original dimensions.

Explanation:

Considering the complete question attached in figure below.

Time period for balance wheel is:

m = mass of balance wheel

R = radius of balance wheel.

Angular frequency is related to Time period as:

As dimensions of new balance wheel are one-third of their original values

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
