I thought insufficient penetration was a welding discontinuity but apparently wrong!

Most texts and the standard identify the tolerance zone for circularity as two coaxial circles.

Option C is the right answer. A wrench uses wheel and axle as simple machine to turn a bolt. The wrench and bolt act as wheel and axle. As rhe wrench spins around the bolt, it turns the bolt just like other spinning wheels turn its axle.

The correct answer to this question is D. Fiber saturation point is used to denote the point in the drying process in wood that only water in the cell walls will remain. It is the minimum moisture content in equilibrium with a saturated atmosphere. It is the estimated point at which shrinkage begins. It is also the estimated point at which a sudden increase occurs inthe compressive strength. Other water called free water is removed from the cell cavities. The fiber saturation point in respect to the moisture content in wood refers to the fact that no free water exists in cell cavities but cell walls and saturated.

Tensile strength s a more accurate term for testing of material.

B A heat treat crack

Most texts and the standard defines the circularity tolerancs as two coaxial circles.

C'mon John, we need more than that. This isnt helpful

This is very much the case. The reason is because a sharp chisel is going to take less time to use. It’s like a knife. When a knife gets blunt, it doesn’t cut. It rips and tears. That’s why a lot of people choose to sharpen their good cutting knives. It’s the same with a blunt chisel. It won’t get into the material as well, since the edge has dulled, and it’ll take longer. You could even risk missing the material and hurting someone if the edge of the chisel slipped accidentally because it couldn’t get into the stone or whatever you’re trying to break up. So, the takeaway is that you should always use a sharp chisel when you can.

The ingot is usually seen in metal place because it is a block or some other shape that is made of metal and shaped into an object. Stringers are known as the fine lines that are likely to occur in groups caused by non-metallic impurities. These are present in the original metal and extruded lengthwise. Often, manufacturing companies will have factories to make different items out of metal. These metals are melted down into a liquid and then it is shaped usually into a mold so that it will harden into the correct shape. However, sometimes impurities happen during this process. A line may form in the metal as it is hardening. Also, dust or dirt may accidentally fall into the liquid metal while it is hardening.

1. Improve access to stakeholders. - Correct Answer, no such improvement opportunity inBABOK 6.3.5.5

The process is normally limited to the flat or horizontal-fillet welding positions NOT VERTICAL
