TIN SMITHY & Sheet metal

TIN SMITHY Introduction : Many engineering and house articles such as boxes, cans, funnels, ducts etc. are made from a flat sheet of metal. The process being known as tin smithy. For this the development of the article is first drawn on the sheet metal, then cut and folded, to form the required shape of the article. Allowance should be given in the drawing stage for folding and bending. This allowance depends upon the radius of the bend and thickness of the sheet metal. Sheet Metal Materials : A variety of metals are used in a sheet metal shop such as galvanized Iron, black, Iron, tin, Stainless Steel, copper and Aluminium. Hand Tools : The common hand tools used in sheet metal work are steel, try square, Wire gauge, Scriber, Ball peen hammer, Nylon Mallet, Snips Divider, Stakes, Cutting plier and Soldering Iron. Here, the details of tools that are being equipped by our workshop purpose only are presented. Wire Gauge: The thickness of sheet is referred in numbers known ...

Fluid mechanics VIVA QUESTIONS and ANSWERS

1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter? Ans: It is a device which is used for measuring the rate of flow of fluid flowing through pipe. 5. What is a notch? Ans: A notch is a device used for measuring the rate of flow of a fluid through a small channel or a tank. 6. Define buoyancy? Ans: When a body is immersed in a fluid, an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body. 7. Define meta-centre? Ans: It is defined as the point about which a body...

Isometric drawings for practice in AutoCAD

What is Isometric Drawing? Isometric drawing is a method of visually representing three-dimensional objects in two dimensions. It allows for a clear and comprehensive depiction of complex structures by keeping the scale consistent and eliminating distortion. Isometric drawings use a 30-degree angle from the horizontal in all three axes (X, Y, and Z), creating a pseudo-3D effect where the height, width, and depth are equally foreshortened. Creating Isometric Drawings in AutoCAD AutoCAD provides tools and settings that make creating isometric drawings straightforward. Here’s a step-by-step guide: Step 1: Set Up Isometric Snap/Grid 1. Enable Isometric Snap/Grid: - Type `SNAP` in the command line and press `Enter`. - Type `Style` and press `Enter`. - Choose `Isometric` and press `Enter`. 2. Switch Between Isoplanes: - Type `F5` or `CTRL+E` to toggle between the top, right, and left isoplanes. Step 2: Draw Isometric Circles and Arcs 1. Isom...
