What tool is used to measure curved surfaces?
Tape measure
What is the difference between airfoil profile and airfoil section?
The difference between airfoil and airfoil section is that airfoil is a structure with curved surfaces designed to give the most favorable ratio of lift to drag in a flight, it is used as the basic form of wings, fins, and tailplanes of most aircraft. An airfoil section is the cross- sectional shape or profile of an airfoil. I studied that in sixth grade for a model plane that I did a report on. Researching into things that aren't required can help put you farther into life's riches. Hope I helped.
What is the Curved line connecting 2 or more notes of different pitches?
The curved line connecting two or more notes of different pitches is called a slur in music notation. A slur indicates that the notes should be played smoothly and connected without any separation between them. It is different from a tie, which connects two notes of the same pitch to extend their duration. Slurs are commonly used in piano, vocal, and string music to indicate phrasing and articulation.
Square meters in one ton of structural steel?
It is roughly 7.6m2 per ton of steel structure material. This can be used for approximate calculation.
What is zero conditional?
A zero conditional is a structure used to speak about general truths, containing an "if" clause. For example: "If it rains, the ground gets wet."
