It has become recognized that is Testing Laboratory the best performance can only be obtained if all the springs of a uniform type possess the same mechanical properties. Special Testing Machine for dealing with tension and Compression Springs of helical pattern are to be made use of the machine of very simple designs used for statical tests on springs cannot be used for Compression and Tensile tests. Spring Testing Machine is an earnest effort in this direction. Machine enable load deflection tests of tension and compression springs to be carried out accurately and quickly.

The Cabinet contains the hydraulic unit the hand wheel of the pump and the release valve handle are outside the cabinet for easy operation. This compact base carrier two fixed upright and four horizontal plates. The first and the third plates with two small uprights from an adjustable frame. The second and the fourth plates are fixed. A square threaded wheel arrangements provided for adjusting the height of the springs.

A Bourdon type Gauge is fixed for direct load measurements. One fixed upright is graduated to denote the deflections or tension of the springs for direct readings. A thimble with on arrow mark is provided to facilitate the readings. The machine is capable of accommodating 8" length 1/2" dial. rod up to 4" dia. springs for tension, 6" length 1/2" dia. rod, 4" springs for compression. Scale graduation are made up to 15 cm.

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

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

Carpentry Viva Questions

Q1: Define carpentry? Ans:  Carpentry is a skilled trade that involves working with wood to construct, install, and repair structures and objects. It encompasses various tasks such as measuring, cutting, shaping, joining, and finishing wood to create functional and aesthetically pleasing products. Q2: What are the various types of wood material used in carpentry? Ans:  The various types of wood materials used in carpentry include softwoods (such as pine, fir, cedar, and spruce) and hardwoods (such as oak, maple, mahogany, and walnut). Other wood materials used in carpentry can include plywood, particleboard, MDF (medium-density fiberboard), and engineered wood products like laminated veneer lumber (LVL) and oriented strand board (OSB). Q3: What is the sequence of operations in carpentry? Ans:  The sequence of operations in carpentry typically involves planning and design, material selection and preparation, measuring and marking, cutting and shaping, joinery or fastening, assembly,

Drill Press Parts Diagram and Their Functions

Drill press is one of the best tools that are used to provide efficient services to the people. Unlike hand drill, the orientation and the location of the holes are considered accurately. All the functions and the features of the drill press are performed well, if all the parts of the tools are in the right condition and working properly. Drill press parts diagram better explain the functions performed as every part of the drill press has a unique and separate function. The parts of the drill press include head, sleeve, spindle, column, table and base. Following are some of the parts of the drill press along with their functions: Head The head part of the drill press houses the spindle as it is attached at the top region of the spindle. It is responsible for the spindle movement because the spindle can only move upward or downward. Spindle Spindle is the most important part of the drill press that is used to hold the tool and is responsible for its rotation. The spindle of t

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
