What does it mean for a curve to be smooth?
A smooth curve is a curve which is a smooth function, where the word “curve” is interpreted in the analytic geometry context. In particular, a smooth curve is a continuous map from a one-dimensional space to an. -dimensional space which on its domain has continuous derivatives up to a desired order.
What is a piecewise smooth curve?
The curves we’ll talk about are called piecewise smooth curves, which means that they are finite unions of smooth curves, parametrized as c(t)=(x(t),y(t)), t ∈ [a, b], like in figures 1 and 21 . Our goal is to be able to evaluate the area of a fence that lies above the curve c and under the graph of f.

- Build your way up to sharing more saliva.
- Use your hands.

What is RMS surface finish?
A: RMS (root mean square) is a comparative number as related to surface finishes measured with a profilometer. A fine finish is in the range of 20-40 RMS, a machined finish often is in the range of 80-120RMS, and gritblasted surfaces will be in the range of 400-500 RMS.
How to measure roughness?
Contact Profilometer: This is a very common technique for surface polish samples. It work like phonograph with stylus attached to it
What is the SI unit of surface roughness?
The unit used in the United States for roughness measurement is micro-inches. This unit represents one millionth of an inch, and it is typically written µ in. The corresponding international (SI) unit is micrometers, or microns for short. This unit represents one millionth of a meter, and it is written as µm or um.
How do you measure surface finish?
Surface finish may be measured in two ways: contact and non-contact methods. Contact methods involve dragging a measurement stylus across the surface; these instruments are called profilometers .
