I am having trouble building a Rack for a school project.

I'm pretty new to OnShape and I'm struggling. I need this final piece to be able to assemble my project. I will take any help I can get as I don't even know where to start. 
Thanks.

I'm guessing you're struggling with all the teeth since the other parts are relatively straightforward extrude and hole features.

1. First, model the rack without the teeth - either with less material (stop short of the teeth) or more material (extrude past the teeth).
2. Next, model one tooth with the dimensions provided in Detail A.
3. Extrude that tooth - either adding or removing material depending on what you did in the first step.
4. Use a linear pattern to add the rest of the teeth. There are several of options here depending on how you want to go. Feature pattern is the easy/lazy way, but part and face patterns are preferred since they are less computationally expensive.

I suggest you look into the beginner tutorials. They cover all the basic modeling techniques you would need to design something like this.
