Sketch

Select top plane as reference and draw the below shown sketch by using centre point rectangle the origin as centre point of the rectangle. Now dimension the elements by using smart dimension tool from sketch tab. And draw the circle by using circle tool and dimension it. 
Extrude the shaded area about top side from sketch plane. 
Now select front plane as reference and a draw the below shown sketch by using line tool and make some fillet according to dimension. Now extrude the shaded area. 
Now select the top most surface as reference and draw a circle then extrude the closed area. Now again select the top most area as reference draw a circle and do extrude cut. 
Now create a plane for creating the rib. Selected newly created a plane as reference draw the shape as like shone below by using offset command. 
Now extrude the closed area.

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

sheet metal rectangular tray making

Aim :- To make a rectangular tray from a given metallic sheet. Tools Required MALLET Snip Stake STEEL RULE Ball peen HAMMER Straight EDGE RIVETS Scriber Procedure The given metal sheet is smoothed using mallet. The measurements of rectangular tray (tray development drawing) is drawn on the sheet with given dimensions using the scriber and steel rule. The sheet is cut as per the marked dimensions by straight snips. Fold or bend as per the given order using mallet and stake. Bending is done as per the given dimension using the stake and mallet. Rivet the folded sheet by using the given rivets and hammer. Safety Precautions Each cut you make exposes sharp edges and creates burrs that can slice a finger. Must Use Hand gloves when cutting the sheet. Metal waste also has hazardous edges. So

Welding VIVA question and answers

VIVA QUESTIONS : Q1: Define welding? Ans:  Welding is a fabrication process that joins two or more materials, typically metals or thermoplastics, by melting and fusing them together using heat or pressure. Q2: What is the typical thickness of MS Plate used in general welding workshop experiments? Ans:  The thickness of the MS (Mild Steel) plate used in general welding workshop experiments can vary depending on the specific requirements of the experiment. However, commonly used thicknesses range from 3 mm to 12 mm. Q3: What is the common job material used in welding experiments? Ans:  The common job material used in welding experiments is mild steel. It is widely available, affordable, and relatively easy to work with, making it suitable for various welding applications and practice. Q4: What is the main function of an electrode in welding? Ans:  The main function of an electrode in welding is to carry the electric current necessary for the welding process and to provide filler mate

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

Welding-LAP JOINT

Ex. No :                                                                              Date : LAP JOINT Aim To join the given two work pieces as a lap joint by arc welding. Material used Mild Steel plates. Tools required Welding power supply  Flat file Welding rod Chipping hammer Electrode holder Wire brush Gloves and apron Earthing clamps Shield and goggles Procedure The given workpieces are thoroughly cleaned, i.e. rust, scales are removed and the  edges are filed. The electrode is held in an electrode holder and ground clamp is clamped to the  welding plates and the power is supplied. The workpieces are positioned on the table to form a “Lab joint”. The tag weld is done on the both the ends of joining plates to avoid the movement of  workpieces during welding. The welding is carried throughout the length of the workpieces on both sides by  maintaining 3mm gap between plates and the welding rod. The welded plates are allowed f

Coordinate systems in AutoCAD

World Coordinate System (WCS), User Coordinate System (UCS). There is 4 AutoCAD coordinates system you should know. Absolute coordinate system , Relative Rectangular coordinate system, Relative Polar coordinate system and Interactive system(Direct coordinate system). Absolute Coordinate system: Absolute Coordinates uses the Cartesian System to specify a position in the X, Y, and (if needed) Z axes to locate a point from the 0-X, 0-Y, and 0-Z (0,0,0) point. To locate a point using the Absolute Coordinate system, type the X-value, Y-value, and, if needed, the Z-value separated by commas (with no spaces). Syn: Enter LINE command: L [Enter] Start line at point A: 0,0 [Enter] End first line at point B: 2,2 [Enter] End of second line at point C: 2,3 [Enter] Examples shown bellow. Relative Rectangular Coordinate system: After first points entered, your next points can be entered by specifying the next coordinate compare/relative f

Lathe machine introduction

STUDY OF LATHE Aim To study about the lathe . Introduction                        Lathe is called the father of machine tools. The main function of lathe is to remove  metals from work piece to give a required shape and size. In the lathe the work piece is held in a chuck. The tool is moved at an angle 90_ to the axis. Various operations such as straight turning, taper turning, and chamfering, facing, knurling, grooving, thread cutting, taper turning are carried out. When the operations above set are done automatically, then the lathe is called automatic lathe. Working principle of lathe                       In a lathe, the workpiece is held in chuck and rotates about its axis by means of power. A  single point cutting tool is mounted in tool post. When the chuck rotated the work piece also rotated. The tool moves parallel to the axis of rotation of work piece to produce a cylindrical surface, where as the tool moves perpendicular to the work piece to pro
