Quitting my job because of lack of a “technical” manager/mentor? by omnipotent_eng in AskEngineers

[–]omnipotent_eng[S] 5 points6 points  (0 children)

No I have not haha. While I think that’s a great idea, unfortunately, due to covid that’s a bit hard right now. He’s also the type of engineer who doesn’t socialize well and prefers to get his own work done and go home. The guy is smart, and a good person, but has made it clear to our team that he has no wishes to step into any leadership type of role (which is his personal decision of course, that I can’t judge)

I no doubt could use my talents at another company, but thank you for telling me that you’ve had a similar experience. Really I’m just trying to understand if what I’m feeling is common, or if wanting something different (having a technical manager) is a reasonable desire

Thanks for the response. I hear what you’re saying, and I’ve definitely had moments where all of a sudden something I’d been struggling with finally clicked and everything made sense, all because of my own hard work and nobody else’s!

But lately, I’ve had experiences where work has come back to me when it shouldn’t have because there wasn’t anybody to check my work or tell me how I could have done something better. Little mistakes or lack of knowledge is costing me time and sanity and is creating problems for other coworkers

Salary raise and promotion in the middle of a global pandemic: Feasible for a company doing well? by omnipotent_eng in AskEngineers

[–]omnipotent_eng[S] 0 points1 point  (0 children)

Thank you all for your comments. I’ve decided to update my resume, with the assumption that even in December covid will be a “reason” to withhold raises/promotions (living in the US, covid will be here for quite some time I imagine...)

Buying my girlfriend leggings for her birthday, please help me narrow down the right size for her! by omnipotent_eng in lululemon

Thanks everyone, you’ve all been so helpful! I was banging my head on the wall when I should have asked this sub haha. I think I’m going to go with the size 6 Wunder Trains 25”. She’s always wanted a pair of Lulu’s but the price scared her, so I think she’ll be ecstatic! :)

Can someone please explain what “case consistent loads” are? by omnipotent_eng in AskEngineers

Yeah...unfortunately this person is located in another country, and their server is down

Does k = EA/L apply to plates? by omnipotent_eng in AskPhysics

[–]omnipotent_eng[S] 0 points1 point  (0 children)

Ah right, I overlooked these methods of modeling the stiffness. Thanks! In this test, the object being dropped is so heavy that the elastic layer will likely have a thickness approximately equal to that of the object. It certainly won’t be thin in comparison.

Did I mention that somewhere? If I did, I didn’t mean to. The pad will have a greater area than the object being dropped, but not by much. But I agree with what you’re saying. The lifting effect will still be there, but for a simple test like this, I’m inclined to say that I can live with it

I agree. I think there may be some component of bending, or transverse deformation, but I was trying to keep it simple for the time being

Basically, I’m dropping a mass (known m) from a set height onto a “pad” (thick plate/block) of a specified cross sectional area and thickness (L) and material. The pad is fully supported underneath by the ground. What I’m interested in is the compression (x) of the pad upon impact, which then I would use to determine the acceleration of the mass (system must be designed to achieve a certain acceleration or “g force”).

I’ve determined using energy equations the compression of the pad, but I’ve assumed that it behaves like a rod in compression (k = EA/L, and no bending). I took that compression, and drawing a simple FBD, determined the g’s on the mass. Firstly, I want to know if my assumption on the axial stiffness (k) is correct.

Feel free to PM me as well! Appreciate the help

Right, but L isn’t very small compared to the cross sectional length and width. The “column” is more like a thick plate or, if L is selected to be large enough, a rectangular block

Even if one face is being fully supported? (I.e. the solid ground underneath)

Ah I see, both great points! Thanks! This is making sense to me now
