Sheet metal is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are constructed with sheet metal. Thicknesses can
Fitting means preparing matching parts to touch or join each other in such a way that one will turn inside of another and will slide upon another or the part hold tightly together. Click here to know more about Fitting
A lathe is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling,drilling, or deformation, facing, turning, with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation.

The Rockwell hardness test method is the most commonly used hardness test method. The Rockwell method measures the permanent depth of indentation produced by a force/load on an indenter. The Rockwell scale is a hardness scale based on indentation hardness
Impact Testing is used to measure an object’s ability to resist high-rate loading. It is usually thought of in terms of two objects striking each other at high relative speeds. The Charpy/Izode impact test (or Charpy V-notch test) is a standardized high strain-rate
We are required to calibrate the Ammeter to know about its error and adjust it to get near to ideal readings. In this practical we will show you how to calibrate the ammeter using a Potentiometer. Practical of calibration of Ammeter using Potentiometer
Specific Resistance is a measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l (Law of Resistance), where R is the measured resistance of some length of the material, A is its
Stefan’s law states that the energy radiated per second by unit area of a black body at thermodynamic temperature T is directly proportional to T4. The constant of proportionality is the Stefan constant, equal to 5.670400× 10–8 Wm–2 K–4. This practical will
We are required to calibrate the Voltmeter to know about its error and adjust it to get near to ideal readings. In this practical we will show you how to calibrate the voltmeter using a Potentiometer. Practical of calibration of Voltmeter using Potentiometer Watch
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. In this practical we will show you how to determine the coefficient of viscosity of water by Poiseulle’s Method. Practical to
