Hi. I'm curious about whether there is any unacceptable risk associated with making a rectangular hole in an external house wall.
In the picture, the wall is a no fines wall. That is, its made off pebble aggregates (20mm dimmer) coated in cement. There are many voids. It's a wall developed by...
Hi. I'm rather new to automation. I'm looking at the operating manual for an auger valve controller (ValveMate 7194 by Nordson). But, I'm unsure about EOC. My understanding is that when an INIT signal is received, the controller actuates the dispensing valve according to the program that has...
In the UK if you wish to put up a retaining wall under 2m high, as long as it is not near a highway or next to building foundations, you can - without planning permission or advising building control. What DIYers do when building a retaining brick wall, is take note of construction guidance...
Hi. Can someone please explain the technical specifications mentioned in the attachment? Thank you. The tool is a hand shear. I understand 2 of the 5 only. First shows thickness that can be cut, and fourth shows length of cut. But, don't understand 2nd, 3rd and 5th...
Hi. This is not coursework, I'm trying to understand the subject.
I read that one method of hardening a metal is through strengthening with a second phase.
I'm not entirely sure I understand the phrase "strengthening with a second phase".
Can the phrase "strengthening with a second phase" be...
I have a piece of wire mesh 460mm x 290mm. It needs to be supported on a frame arrangement to stop it sagging when I place (light) things on it. The mesh will simply sit atop the frame, not actually be affixed mechanically to it.
Let's say the frame edge is 1/8" wide stainless steel angle, and...
Hi. I'm using a free copy of Coral Draw to make a graphic of a type font. It's easy, you use the Text Tool (which draws upon a font file somewhere on your PC), then you scale the size up to what you want. And the drawing of the font is smooth-lined. Even on large magnifications.
But the drawing...
I'm a novice. I presume that normally you make sure that the metal in a structure does not undergo stress beyond it's yield point, or elastic limit. Although, I suppose, if the metal is stressed anywhere between the yield point and Ultimate Tensile Strength, the material is holding, it's just...
I was just wondering how much money, potentially, you could save, if you could make your own die at home. But, how plausible is that? Dies made of are very hard metal.
I'm a novice at engineering. As I understand it, coining requires high pressures and it induces plastic flow of the metal.
Okay, let's imagine that I want to produce a 2" diameter medalion and I am going to fill in fields I create with enamel. I want a 1/16" high raised lip say 1/16" wide near...
From what I've tried to glean from the internet, the usual requirement to establish proof of concept, is to build a rough prototype. If that rough prototype works, according to some established crieria, then the concept is proven.
I believe the actual concept itself can be very simply...
