H01- Introduction to Hydraulics

    The fluid power has been used from ancient period to till now in various form. In earlier day before development of technology the river flow is used to transport timber from upstream to down stream later followed by external, internal engine an turbines are as made use of fluid power and now we see earth movers and other instruments which make used of hydraulic power and thus we made our work economically easy fast.
    Here the fluid is corresponds to the material which flows, which my be either gas or liquid. In hydraulics we makes use of properties of liquid to transfer power.

What is Hydraulics?

    The hydraulics Is the Technology/science of make use of liquid, to transfer power through the liquid under the pressure. It makes use of properties of liquid such as density, viscosity, compressibility etc.

Why the name Hydraulics?

The word hydraulics is derived from the Greek word ”Hydra” means water and “aulic” means pipes.

How we can get work from liquids?

    We can take/get the work from the liquid by setting an arrangement of various hydraulic components in sequential form to perform specific task.
The control system/ arrangement that controls OR transmits hydraulic fluid is known as HYDRAULIC SYSTEM 
The hydraulic system makes use of Pascals law and continuity equation.

What is the basic idea behind the hydraulics?

Above fig. shows the  basic idea behind the hydraulics that is when a force is applied at a point on the confined in-compressible fluid is transmitted to another point.

    The major function of a hydraulic fluid is to provide energy transmission through system which enable work and motion to be accomplished easily with the less effort. 
The fluid flows very easily with accuracy and flexibility by maintaining ability to transmit maximum power by weight.

T01- Introduction to Turning on Lathe

What is turning ? Turning is a machining process used to generate cylindrical and conical surface by rotating the work piece and with the help of cutting tool. The machine where the turning process is usually carried on is called as lathe , where a cutting tool is fed against a rotating work-piece. What is the working principle of Lathe? The principle of operation is shown in the figure. Here both the work piece and the tools are rigidly held on the lathe. Then the tool is provided with longitudinal and transverse movement while the work-piece is being rotated at suitable speed. Basically three type of major surface can be produced depending on the movement of the tool, They are as follows:- I. When the tool moves parallel to the axis of rotation of the work piece, a cylindrical surface can be produced. Which is as shown below. II. When the tool moves at an angle to the axis of the work piece, a tapered surface can be produced.  Which is as shown below. III. When the tool moves perpe

Jowar (ಜೋಳ)

It is flowering plant belongs to grass family Poaceae . It is also known as Sorghum, which is cultivated extensively in India and other country. Earlier Jowar was used in food made for animals but now people have started incorporating it in their diet due to its incredible health benefits. Now a day all bakery and homemade dishes make uses of all-purpose flour/Maida which is not good at all for health. A healthy alternative to all-purpose flour is jowar. This is rich in protein, Potassium, Calcium and other minerals. Since the jowar is gluten free, it plays a critical role in cellular function and repair. The rich quantity of Potassium & Phosphorus helps lower cholesterol and mange High B.P. The grain is incredibly rich in fiber and hence should be part of diet.

T02- Precaution to be taken on Lathe

Before working :- - Ensure that the electrical power supply is as needed for the machine. Ensure that the safety guards are in proper condition.  - Ensure that the work area is clean and tidy. - Ensure that the meshing gears are in proper mesh, and the power feed levers are in neutral.  - Ensure that the automatic lubricating system is functioning.  During working:- - Shift the levers to change the speeds and feeds only when the rotating parts are fully stationary.  - Wear an apron (not too loose) with the sleeves of the shirt folded. - Avoid wearing rings and watches when working. Wear shoes to avoid injury to your feet.  - Remove the chips by a hook, and use a brush to clear them.  After working:- - Clean the machine with a brush and wipe with cotton waste.  - Oil the bed-ways and the lubricating points.  - Clean the precision instruments and hand them over to the instructor for safe keeping. - Clean the cutting tools and place them in their respective places.  - Clean the area surro
