THE BIKE HOUSE on Upshur is closest to you if you live out Wisconsin Ave. I know nothing about them, because I have long been gone from Washington.
Also one listed in Arlington. Good luck. A basic principle of bike co-ops is to support the sort of bicycle you're trying to fix, and to keep them in use.

OTOH if it doesn't wobble, and you can turn the right crank without play or hearing or feeling the bearings grind, then it's safe to assume that it's isolated to the damaged left arm.
Note also that BB play is felt more as slop or clicking/clunking, whereas the sensation that your foot is rocking as you pedal indicates a bent crank arm or pedal shaft, or as on your case the pedal half torn out.
In any case, the DC area has a few co-ops, (search bicycle co-op near DC) and I'm sure one can help you get this bike rolling for small dollars.

Hi, folks. I've had an old Free Spirit since 2010. I know it was a cheap bike to begin with and it's probably worth... $50 today...? Maybe. Not fancy, but it's been a good friend since we met.
Recently I got it new tires and was hoping to keep it alive. But then the left pedal got crooked. I took it to the shop and was told that the best to do would be to replace the entire crankset — and that it would cost me more than $200.
That's why I need some advice... How do I figure out which parts to order if I want to replace the entire crankset? This is a labor of love — it'd be a shame to see her die after all the places she's taken me... Your good advice will be greatly appreciated.Thank you!

It is a regular one-piece crank. Find any other parts bike with a similar looking crank and you will be able to swap the entire assembly, bearings and all right into your bike. I have swapped cranks from one old 70s USA brand into another old USA brand of the same era, and BMX cranks/bearings etc. from the 90s into a USA low-end road bike that was 20 years older than it. You can find old parts bikes for $1 to $20 very, very easily. Make sure you never go back to that bicycle shop as long as you live, they are obviously very ignorant or complete criminals. Go buy an old book on bicycle maintenance and it will show you how to do this work on your bike, it is so simply that after you do it once you will be able to do it with a blindfold the next time.

Then you are in luck. A square-taper bottom-bracket spindle will swap right into your bike and allow you to bolt on any square-taper crankset you want. Or you can wait to find replacement parts for your bike that match the originals. Put up photos of your current equipment. I think I have a few extra cottered crank spindles in the garage, also I have a set of cottered cranks I think are in good condition, and lastly I have a stock of new cotter-bolts, maybe in two or three different varieties. Different countries used different standards for their cottered cranks !!! I respect the history of the cottered crankset, it was very popular on bikes for decades, and before the square taper design became popular it may have been said to be the "high-end" type of crankset.

Been way too long since I've been in geometry class. Just asking!

I would describe the spindle as a 3-dimensional rod, not a 2-D circle. Isn’t what you’re describing a chord?

A perpendicular depends on at least two lines being 90° from each other. One of those lines can be another surface. Typically a flat surface or plane. If a spherical surface or circle can have a line through it described as perpendicular, then the line or chord would have to pass through the center of the sphere or circle. A cotter bolt does not.

The axis of a cotter pin is indeed 90 degrees from the axis of the spindle. Just as the crank arm is. Not sure why this is so hard to grasp.

Axes don’t need to intersect for them to be 90 degrees apart.
Listen, you have admitted that your geometry chops may be a little off; I’m sure you can take a rudimentary geometry class at the local community college.

On my ride today I saw this guy on a Free Spirit and chased him down and had a talk with him. Adam said he had bought his-and-hers Free Spirit bikes at a yard sale a while back and has been riding this one. He had no problem letting me snap a photo of it so here you go:

If two lines don't intersect, then can't be perpendicular. There is a line from the midpoint of the cord that is perpendicular to the chord and also intersect the center of the circle. I just don't get why perpendicular really applies here and your rudimentary geometry knowledge can't even come up with a logical reason you can relate to me, and much less a theorem.

Sounds like you are imagining planes going through the two that can be ninety degrees to each other. There are also planes that can go through them both that are parallel to each other.

I just don't get why perpendicular really applies here and your rudimentary geometry knowledge can't even come up with a logical reason you can relate to me, and much less a theorem.

Listen, you clearly don't know what "perpendicular" means, and maybe you don't even know what "90 Degrees" means. Personally, I think the wedge of the cotter is what's confusing you. But I digress. It's a waste of time for me trying to explain it to you. Good luck in your 3D world.
In elementary geometry, two geometric objects are perpendicular if their intersection forms right angles (angles that are 90 degrees or π/2 radians wide) at the point of intersection called a foot. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. Perpendicular intersections can happen between two lines (or two line segments), between a line and a plane, and between two planes.
I still wouldn't describe a chord as perpendicular unless it also ran through the center of the circle. And the cotter bolts I'm familiar with do not go through the center of the spindle/axle.
