    It appears you're using a cyanoacrylate glue ("Super Glue") to attach your gussets. I've been a carpenter and woodworker for 45 years (everything from framing to cabinetmaking), and whenever I've needed a maximum strength bond between wood pieces, I've used a respected and popular glue. There are several, but I greatly prefer Titebond products. (I have zero connection with the company--just speaking from my own experience.) Occasionally I'll use epoxy and, on rare occasions, and for temporary purposes only (such as holding a workpiece in place while I saw or plane or rout the workpiece), I'll use SuperGlue with a spray activator. There are other wood glues, of course, but if you watch the woodworking channels of people who know what they're doing, you'll see the Titebond label on almost all of them. SuperGlue? Rarely. Gorilla Glue? Forget it! Messy, porous stuff. As for the stresses and other engineering issues, those are above my pay grade, but for wood to wood connections, use a recognized and respected brand of glue. Also, although TiteBond usually cures to 90% strength within an hour, I'd give your connections 24 hours before testing, so as to eliminate any possibility of uncured glue weakening your joint.

    In a truss, the load should be applied only at the joints. So whether you load it from the top or bottom the load should be applied at the joint. The members are not designed to take bending loads. Also the joints need to be pin jointed otherwise bending moment is produced in the members leading to unexpected failure.

    I have a degree in geology, got my first job in hydrology, and kinda fell in to civil engineering. I took and passed the FE because I took enough masters engineering courses the state let me sit, but I didn’t finish the masters so now I’m in this weird state where I’m an FE that can’t get his PE in some states. Some states will let me take the test after 8 years instead of four years of experience, but honestly it’s frustrating and just seems like a weird technicality that prevents me from taking it despite having taken most the math and science courses engineers take anyways. Maybe I should just go back and finish my masters, but I don’t want to take on more debt. It’s kinda silly honestly.

    Weak glue but most importantly your staples should be aligned exactly as the 45° sticks do, and the three intersecting axes in a nice should intersect at one point ideally, or as close to that as possible.

    I left high school early when I lived in Germany to get a bachelor's in Game Art & 3D Animation. I now have a full time job in that field but space has always called to me so I am currently saving up for the next 2 years to get into Aerospace engineering (astronautics). I currently suck at math since I left high school early and am trying to "re-learn it" but I definitely do enjoy doing math. Over the next 2 years while I'm saving up money I am also going to need to get my GED, do the SAT and then apply to the college as well. Do you think all that's possible within that time frame? I'm 21, almost 22 now so I'll only be starting at 24, but if I can get a bachelors in AE I'd have a bachelors in 3D, bachelors in AE, and I'm also a MENSA member by the time I'm around 28.

    I’ve found it that actual jobs are much easier than school. I love my job but I hated every aspect of school. They should award degrees based on your work performance where you learn most of the stuff you need to learn pertaining to what it is that you want to do such as completing projects etc.

    Parallel axis theorem. The one with metal cylinders on the outside has masses that are further away from its centroid thus a higher mass times r^2 value is added to the metal cylinders' moment of inertia, thus a higher net moment of inertia than the other object. Both objects have the same force/ torque on them(gravity on an inclined plane, same slope and same weight). The one with the higher moment of inertia will have less angular acceleration.

    Another explanation: both disks start with the same potential energy at the top of the ramp (same mass and height) and assuming they both experience similar friction, they will have the same kinetic energy right before they hit the bottom. As they're rotating, the total kinetic energy they have is split between linear and rotational kinetic energy, meaning the more energy it takes to rotate the disk, the less energy it can dedicate to moving down the ramp. The equation for rotational kinetic energy is .5Iw^2. I is inertia. The disk with the weights at the center is closest to a cylinder, so equation for inertia would be 1/2mr^2. The one with the weights toward the outside is closer to a ring, which has an equation of mr^2. Therefore the disk with weights toward the outside will have a higher inertia, meaning the rotational kinetic energy will be greater and the linear kinetic energy will be less. In conclusion: 🤓

  • @muhtasimrahman8188

    The one with a larger moment of inertia will travel further since it releases its built up rotational kinetic energy over a larger period of time.

  • @markstice2098
    @markstice2098Ай бұрын

    I don’t think so. I think the one with the lower moment of inertia in theory may travel a bit more due to a bigger acceleration

  • @muhtasimrahman8188
    @muhtasimrahman8188Ай бұрын

    @@markstice2098 I actually think you are right. The lower inertia wheel will travel further due to its greater speed. More of the energy is being used to move the thing forward rather than spinning it up. kzread.info/dash/bejne/lGuuudmoacfImbg.html

    Go sit on a spinny chair, and take the biggest swing you can make with your legs and feet to start spinning with your feet off the ground. First start with your legs stretched out as far as they can go, and then quickly fold your legs inward, going into a partial fetus pose. Notice how you spin faster despite no external force being applied to you after you pulled your legs in? It's the same principle as to the reason why that disk will spin faster.

    Well done, video, and I agree with everything you said. This hits close to home as a Sr. electrical engineer without a degree. Yes, I'll explain. I studied and learned everything I could in electrical/ mechanical engineering for about 6 years on my own, researching all core curricula and buying the textbooks, and, yes, I did the work. I worked construction 8 hours a day, got home, and studied 4 hours every night for 6 years because I didn't have the money for college. I did have to shell out the money for a college course in CAD to get a student license to AutoCAD back in 2011, which really ignited my productivity. I loved what I was learning and just genuinely hated the sole-suck in the classroom. I designed and built everything I could, from CNCs, computers, and Tesla Coils; you name it. If it was geeky and technically complicated, I was obsessed with it. I spent every dollar I earned on the software, equipment, tools, and projects. Then I lucked out and landed a job as a mechanical engineer at an RV company, which I held for 5 years; I took classes at night when I could then lucked out again and landed a job as an electrical engineer at an EV startup and have moved into the Sr. Electrical engineer for the last 3.5 years. It has been extremely difficult to do this without a degree, but I have put in thousands of more hours over these 14.5 years to gain this knowledge I have, and that was only possible because I love electrical engineering, physics, and computer science at the very core of my being. Each employer placed me under much higher scrutiny, and it was a good thing that I had put in all the long nights. My ability to teach myself has been extremely valuable and has allowed me to crush other engineers' productivity on new complex problems. Again, I have put in 4 times more work than a four-year degree would provide, and I have spent much more money on my projects to learn EE skills than I would have spent on a degree at this point. Getting a foot in the door has been extremely difficult, and I recommend getting that degree. My situation is extremely rare and an unnatural blend of hard work and excellent luck! I am still going to school at night, but the classes are incredibly tedious and even more difficult at this point. You will likely be slapped in the face by the importance of the soft skills in the workplace that are buried in the hard skills in college. One of the pain points I did avoid was knowing what I was interested in before taking any classes, not plugging through a year of school to find out I wasn't interested in the field. I could write a book on this topic. To summarize this topic from my life experience, I want to get a degree. If you love engineering, nothing will stop you from learning however you can, but it will be almost impossible to do what you want at the company you want to be at. Would I consider a candidate's experience and passion projects grounds for hiring?.. Yes, but that's because I can recognize my own traits in others that have led to my success. Are you likely to be interviewed for an engineering job by me?.. Probably not. I wrote a lot here, but hopefully, this will provide first-hand input. Also, I am currently in college, nearing the completion of my BS EE. Regardless of my job title and experience, until I get that degree, I will not really call myself an electrical engineer.
