Hello /Sci. I'm no engineer by any means but I am sometimes creative. I'm thinking about trying my hand at building a roof rack system for my car, because I'm cheap and don't want to shell out 500 bucks to buy one. Anyway, this is the design that sort of makes sense to me, excuse the awful drawing, does it make sense to any of you?

Goddammit, sorry it's upside down, I have no idea why
I suppose you can help me with this quick problem:
20% for rain on Saturday, and 30% on Sunday. What's the probability for rain in weekend?
>>8080334
.2*.3+.2.*.8+.3*.7

I'm here for more of the physics side of it, like will the bolt setup properly apply inwards pressure. Not so much actual design

wew whaddafug i flipped it and its upside down again
>>8080340
ehhhhh
doesn't look like it'll work well
you'll get a lot of flex at the bottom.

Let's say, hypothetically, everything is un-bendable and totally solid. I will be reinforcing the spots that need it. This is, obviously, a very basic sketch
>>8080352
hypothetically, yeah, looks ok, but the countermoments are so close together you're going to need to use a lot of force to get them to balance
just have a single bolt top and bottom
>>8080354
My apologies but I dont understand what you mean by single bolt top and bottom. The point where the red and green bars meet is a pivoting point. Lengths and angles will be tweaked with at a later time when I actually start using proper dimensions.

Thank you, kind sir, I can't believe I didn't think of this
>>8080334
25% ?
>>8080337
K, mind xplaining what are you doing here?
>>8080380
It's high school stats man just google it
>>8080334
= 1 - probability of sunny both days
= 1 - (1-.2)*(1-.3)
= 44%

red parts will slowly move down because the car rocks a lot. And because it will flex easily. Support it at the center of the roof or don't be a cheap skank.
