Engineering Question
Conditions:
A backhoe weighing 22 tons is on top of a lowboy trailer and heading east on Interstate 70 near Hays, Kansas . The extended shovel arm is made of hardened refined steel and the approaching overpass is made of commercial-grade concrete, reinforced with 1 inch steel rebar spaced at 6 inch intervals in a criss-cross pattern layered at 1 foot vertical spacing.
Solve:
When the shovel arm hits the overpass, how fast do you have to be going to slice the bridge in half ? (Assume no effect for headwind and no braking by the driver.)
Extra Credit: Solve for the time and distance Required for the entire rig to come to a complete stop after hitting the overpass at the speed calculated above. Yes, you can neglect friction.
I couldn't solve it either......but who cares; the pictures are great!
P.S. The driver was on his cell phone...............

Well, I have driven on the interstates in the states, and I've been tootling along at about 75 keeping my eyes open for cops, and been overtaken by flipping huge lorries!

I bet he was giving it some. IIRC they have no limiters on their trucks by law!

Major clanger from me. Checking the 3.5t tpper over pre MOT. Think I should do it more often really.

Reckon there's 1.6mi left?

I think you probably have had your monies worth out of that one.

Obviously wasn’t a ‘pair’ with the one next to it?

Possibly. Or it could be that my neglecting to get round to fitting the valve extension for the inner meaning that tyre pressures were never checked on the inners.

I had to change all four rear tyres :oops: and did the valve extensions. Still failed but not majorly.

Yesterday afternoon after I brought it back I did a touch of welding under the wheel arches. Been meaning to do this properly for ages, would rather have done it in summer but hey ho. I steamed it off, cleaned it up further with a screwdriver and abrasive stripping disc then cut the worst out. Gave the rusty bits a good coat of Vactan (think somebody here recommended it) after heating the arch area with a fan heater.

The sealant is Multistick. Have used it for body panels very succesfully before. It's been used where it's too shite to weld to, and then around the edge to make it look like a continuous weld as per regulations. Which we know are impractival and bollocks, and it's not structural either- just near the support bracket to the chassis (which they put down as near suspension mount?? As if tin worm was a pathogen that spreads like a hospital infection) Anyhow, by the time it's covered in this which I'm currently warming up:

it'll look pukka.

Talking of bollocks regulations, it failed upon emmissions. New regs from May last year mean that the emissions must meet manufacturer's specs. As per this label:

0.75?? It clocked in at 2.08 last year. With a year of religious Miller fuel conditioner use, it's now down to 1.46. No way in hell will that get down to 0.75. As always, the clue is in the wording of the regs that they try to hide from Joe Public. Here ya go:

Gotcha! Off with the sticker. It's clearly the wrong value anyhow, 0.7 is Euro 5 ffs! Not a 2003 pre common rail Transit engine. I don't feel bad for 'cheating' the test at all.

I'll take your OOps and raise you one from Bristol................................

A truck crane within a construction zone on a UK highway became wedged under a bridge, causing hours of delays near Avonmouth, Bristol, on Monday. A video clip of the incident was uploaded to Facebook by Scott Davies, a work colleague of the man who filmed it. Within the clip, the crane is shown halted at the bridge, seemingly stuck against the overpass.

A spokesman told Deadline News, “The safety of our road users is paramount, and the road was closed following the incident while structural engineers carried out a full inspection and assessment to ensure the structural integrity of the bridge.”

Thorough inspection revealed that the bridge structure was not damaged, however some minor surface repair work was needed. Highways England is continuing to investigate the incident.
