We will see about hacksaw used for which purpose and hacksaw definition and uses So without wasting any more time move towards our topic.I already write about engineers files and types of files. you should have idea about this it will help you to enhance your knowledge about workshop technology.
The hacksaw


hacksaw is generally used for cutting of metals.Where large amounts of metal waste must be removed, this is done more easily by hack sawing away from extra metal rather than by depositing.
Hacksaw Definition hacksaw is a hand tool which is used for cutting of metal.
Construction and working of hacksawIf the work-piece is left a little too large, then a file can be used to obtain the final size and surface. The hacksaw blade fits into a hacksaw frame on two holding pins, one of which is adjustable to tension the blade. The frame of the hacksaw should be rigid, keep the blade in correct alignment, stretch the blade easily and have a comfortable grip.The blade is mounted on the frame with …

Today we will learn about engineers files explained, as we know hand tools are used to remove small amounts of material, usually from small areas of the workpiece.   Do you know why hand tools are used ?Hand tools are used because of following reason: If no machine is available, The workpiece is too large to go on a machine The shape is too intricate or simply that it would be too expensive to set up a machine to do the work.As you know the necessity of a hand tools now we will know about a hand tool , engineer's files.
Engineer’s files

Files are used to perform a variety of tasks, from simple removal of sharp edges to producing complex shapes where use of the device is impractical.Files can be obtained in a variety of shapes and in lengths from 150 mm to 350 mm. Single-cut file:When a file has a single series of teeth cut across its face it is called single-cut file,Figure of single-cut file is shown below.double-cut file:When a file has double series of teeth cut across its face it i…

Auxiliary ViewsAn auxiliary view is one projected from the front elevation (not in the positions occupied by the side elevation or the plan) to illustrate more clearly some important feature not seen in the other views. It so happens that the important feature is usually a face whose true shape is required.
Definition of auxiliary ViewsAn auxiliary view is a views which is form from the front elevation is shown to illustrate some important features not seen in other scenes more clearly.
Examples of auxiliary ViewsExample of auxiliary views is shown by the given figure of  Auxiliary Views and Projected True Shapes.A auxiliary View and True Shape.Difficult Auxiliary View and True Shape. A auxiliary Views and Projected True Shapes.To explain this point more fully let us first draw the front elevation, plan and side elevation to dimensions shown in given figure.  An auxiliary view can be projected from any viewpoint. However, the "true shape" of the sloping face can only be shown whe…

Biasing the p-n junction means applying some external voltage to both sides of the p-n junction. Reverse-biased junction and forward-biased junction are two types of biased junction. You should have also good understanding of  N-Type and P-Type Semiconductor before moving towards this topic.

Biasing of p–n Junction Biasing of a p–n junction means uses of some external voltage across the two sides of the p–n junction. It is divided into two groups 
Forward-biased junction : When the p-side of junction  is connected to the positive terminal of a battery and the n-side of junction is connected to the negative terminal, the p–n junction is said to be a forward-biased junction. Reverse-biased junction :If the positive terminal of the battery is connected to the n-side of junction and the negative terminal on the p-side, the p–n junction is said to be a reverse-biased junction.Now we will see about forward and reverse-biased junction in detail.

Here you will know about n type and p type semiconductor in details. You can already see about bonding in semiconductor.N type and P type semiconductor is used in electronic appliances.which is the basis of working of all the electronic devices.So lets discuss in this given topic in the details.




N type and P Type SemiconductorWhen some impurities added to the pure semiconductor then it becomes extrinsic semiconductor and this process of adding impurities is known as doping.  Now it depends on the which type of impurities it added to the semiconductor (two types of impurities can be added to semiconductor pentavalent or trivalent). n-type semiconductor : If impurity that is added to the pure semiconductor is a pentavalent ( which has five valance electron ) then it is called n-type semi conductor.p-type semiconductor : If trivalent impurity is added to the semiconductor then it becomes p-type semi conductor.( Note-List of n type and p type semiconductor material is given below.)
It is very…

Are you searching about essay mistakes.Here i am going to share with you about some of the most common mistakes that students make when writing their essays.This will help you write a effective essay. 
Some students simply don’t spend any time on their essays. A lot of bright students think, “I’m number one so I don’t need to take any time on the application.” The result is that it looks rushed. If you want to show some reflection You don’t want to have the appearance that you spent only five minutes on it.Another mistake is the admissions officer doesn’t learn anything. If I read an essay and think, “That’s nice but I don’t know anything more about this student,” you’ve failed. You only have to write something interesting about yourself.

Essay Mistakes Here is the list of essay mistakes that you should have to keep in your mind to avoid common mistakes during writing an essay.
1.Choosing a topic that sounds good but that you don’t careabout.It is essential that you choose a topic that i…
