If 455 that's .030 over is 462 and .060 over is 468, how many cu. in. is .040 over bore?
Would it be 463 or 464?
I know stupid question but I am bored at work slow day for me.

 

I would say because when I had a 455 30 over same as you 462, so 40 over has to be either 463 or 464

 

Come on guys. High school geometry


4.165" bore (4.125+.040), 4.25" stroke, 8 cylinders


[PIx(4.165/2)²]x4.25x8=463.23227427

 

463.2 I get.

Edit: What the guy above me said.

 

I failed geo

 

High school was a long long time ago for some of us.

 

I thought a .030 455 was a 461?

 

455 bored:


.030 over is 461.01 (461)
.040 over is 463.23 (463)
.060 over is 467.69 (468)

 

At 50 years old, believe it or not, I still use geometry every day....


I will admit I let the CAD do the hard stuff like area under a catenary and such

 

Civil Eng?

 

I thought maybe there is a unknown element in the formula because everybody here on CO is calling their .030 455 a 462. That's why I asked.

for all your displacement & compression calculations.

 

Yup

 

Thought so. Mech here, but all I do anymore is project manage and write specs.

 

I do a little of everything. I'm an Estimator/Project Manager/Engineer for a bridge demolition company. Kind of an early retirement job (50 hrs a week & very little travel) after working as a bridge construction project manager/superintendent for 25 years.

 

That's impressive. Both the current one and the previous.

I modify Toyota assembly lines as the models and the desired capacity/vehicle
on each line change. I'd love to blow up a bridge though.

 

Working in the automotive industry would have been my first choice. I started out as a mechanical engineer but wasn't smart enough for things that moved. Civil was a fall back career. (never regretted it though)


We do implode a bridge once in a while (CDI is the explosives subcontractor we generally use)




Buildings too:




Generally we take them down with big hammers and shears


(kind of got off the subject, didn't we )

 

Indeed we did. Great videos though.

Ahem *cough* (adopts a sonorous southern politician voice) There is no REPLACEMENT for DISPLACEMENT.

Carry on.

 

Sorry, but this is pretty basic high school math, and since everyone here is using a computer, there's a calculator built right into it (not to mention Excel).

 

Computer? There's a calculator built right into your phone.

Also, you can Google arithmetic problems, and you will get the answer.

come on use a slide rule

 

It was a good exercise in learning html too

squared =&#178 = ²

and

PI =&#960 = π


(although I thought pi looked too much like an "n" so I didn't use it)

 

lol no wonder why u r an engineer .
as you can tell Mike math was not my specialty

 

wow impressive

 

Yet another sad commentary when people need to do that...
