1. TAPE :
CHARACTERISTIC — It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners.
USES — A tape measure or measuring tape is a flexible ruler used to measure size or distance. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool.
2. YARDSTICK:
CHARACTERISTIC — A meterstick or yardstick is either a straightedge or foldable ruler used to measure length, and is especially common in the construction industry. They are often made of wood or plastic, and often have metal or plastic joints so that they can be folded together.

3. HEM CURVE:
CHARACTERISTIC — A convex curve turns outwards (like hemming the outside of a circle) and a concave turns inwards (hemming the sleeve edge of a sleeveless top). A curved hem can be a little tricky if you want to prevent a puckered edge which looks messy and unprofessional. There are several options to sewing a curved hem.
USES — Hemming is a forming operation in which the edges of the sheet are folded or folded over another part in order to achieve a tight fit. Normally hemming operations are used to connect parts together, to improve the appearance of a part and to reinforce part edges.
4. GAUGE:
CHARACTERISTIC — A Strain gauge (sometimes refered to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result.
USES — Gauge, also spelled gage, in manufacturing and engineering, a device used to determine, either directly or indirectly, whether a dimension is larger or smaller than another dimension that is used as a reference standard.
5. FRENCH CURVE:
CHARACTERISTIC — A French curve is a template usually made from metal, wood or plastic composed of many different segments of the Euler spiral (aka the clothoid curve). ... The curve is placed on the drawing material, and a pencil, knife or other implement is traced around its curves to produce the desired result.
USES — French curves are plastic (or wooden) templates having an edge composed of several different curves. French curves are used in drafting (or were before computer-aided design) to draw smooth curves of almost any desired curvature in mechanical drawings.
