    lifting force of a beam

    Hi there, I just have question about how much force is needed to lift the beam at point C. Point B will be the hinge location (rotation allowed but no x and y displacement), Point C is the spot where I want to lift the beam and X would be the overall length of the beam. Total weight of the...

    How much force to lift a beam

    Correct me if I'm wrong but F=0, isn't to see the equilibrium of the beam only?

    How much force to lift a beam

    oh my bad. I will post it in there. Thank you. The total weight of the beam is 1468 lbs and there's attached 50 lbs weight on point the other end.

    Ballistic .50 cal

    Hi there! I am trying to calculate how thick it needs to stop a 50 BMG AP caliber using AR500 plate. I used the formula that DoD published and I was able to get that it needs 0.554" plate to fully stop it. My question now is, since we're using only 1 plate of 0.50" thk of ar500, in theory...

    Stacking an object

    when you say rigid what do you mean? The object I'm referring is a rectangular shape like books but 750 lbs each and 12" is the height per item. I did FEA and it can handle 10 of them without any deformation but the question I have now is, what is the amount of this object can be stacked on top...

    Stacking an object

    Good Day, I am just wondering if there's a direct way to calculate how high we can stack an object on top of another before it becomes unstable (wobbly) where it can fall into someone? Let's use the book analogy, the object will be rectangular shape and let's assume they aligned properly. Any...

    Stress Distribution

    sorry for the confusion, I don't want to use the Simulation software for it since I only have Solidworks and there's no way it can do it. I was wondering if there's a way calculate it by hand? formula to follow? so I will know how many percent less is the force after the first impact and apply...

    Stress Distribution

    Hi, this is a structure that we designed to decrease the force as the absorber breaks (thin plates that is designed to break upon impact). My question now is, is there a way to calculate the force after the first contact with the first plate? because I know the 1st plate will be destroyed and...

    Pull out force

    Let's say I made hole to install a post and the hole is 2'x2' and filled it with #4 rebar and 3000 psi concrete how much force from the top it can handle without pulling out? The question is mainly to know how much force per square foot does #4 rebar has combined with the 3000 psi concrete.

    Foundation Design

    Good Day I wanted to know if there's any article/site/resource that can give the formula/calculate the pull out force of the whole foundation design? This is a metal frame that will have rebar reinforcement on all sides. The two sides has both 60" of rebars and the width will only have 30" of...

    Friction

    Hi everyone, I tried searching more about this question but I'm getting different answers from different websites/forum. I might as well ask it here. This piece of rubber is 4"x2.15", it's not much of surface area but better than nothing at all. My question now is, is it really true that the...

    Geometry

    Hi there! I am wondering what could be a great shape/geometry I could change/add to this stand (circled part) This stand is meant to fall down on its back but apparently on smooth surface it just slides and does not tip over. What do you guys think? I am wide open to suggestions/idea. Thank...

    Aerospace Engineer

    Hi there! Glad to hear that. I just started my first engineering job and currently working as an R&D Engineer. I love what I'm doing right now, it's great learning experience but I'm just preparing myself down the road. I am thinking of staying on this job while studying to get my MSAE for the...

    Aerospace Engineer

    Good Day Engineers, To the people that has degree with Aerospace Engineering, how are you guys doing so far? I am planning to take Masters in Aerospace Engineering and wondering how is your job satisfaction? feeling about your career? work and life balance? and lastly the pay? I finished my...

    FEA Help

    Can you enlighten me what equation is that? it's been a while the last time I did statics and strengths of materials 😅 Thanks!

    FEA Help

    Hi there folks! I have this tube with reinforced steel plates on 4 sides. The plates helps big time and lessen the stress concentration for about 40% less. My only concern is, the max stress is still higher than the yield and tensile strength of the material. There's only few things I can do...

    Foundation Design/Idea

    Hi there! I am designing a fixture to test a webbing. The impact force of the vehicle we'll crash is 104000 lbf. I was able to design a fixture that can withstand that force but the question is how can I keep this fixture stay in the ground. Concrete anchors? Dig a hole with metal and pour...
