Force and Pressure are the two important concepts of physics which are often erroneously interchanged by the people. But, these two are not same at all, as there is a vast difference between force and pressure, we will discuss about the difference between them in this post.

We have all seen photos of anticipated upcoming models wrapped in black padding and crazy checkerboard and swirl patterns, and might have wondered if all that is really necessary.We will discuss the reason behind wrapping the new cars in this article.

While much of a new car or truck’s development happens behind closed doors, there’s no substitute for real-world testing on both private tracks and public roads, at which point a test vehicle – called a “mule” in automotive language.After manufacturing every vehicle has to be tested on road to see how it behaves.

Manufacturers are known the difference between two blow moulding processes. It is quite difficult to understand the difference. Here we will explain the difference between injection blow moulding and extrusion blow moulding.

Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores. When the wheel is in use, the abrasive grains cut into the material that is being ground, removing the unwanted surface material in small chips.

You might have seen industrial floors marked with various colored strips. Some of the strips are colored yellow and black, red and white, and so on. In this article, we will discuss the meaning of various colored strips that are used for floor marking. 

Face of tooth:It is defined as the surface of the tooth above the pitch circle is known as face.

Generating green energy is one of the major problems of this age. All over the world, inventors have strived to harness solar and wind energy but the efficiency leaves much to be desired. The Vortex Bladeless windmill is a revolutionary technology that promises to change the discourse surrounding renewable energy. The windmill is designed like a micro wind turbine that looks just like any other pole stuck in the ground. Free from the giant blades that are typical of conventional windmills, this windmill operates using the vortex shedding effect.

Generally rail tracks are made in I Section.We might wonder many times that why any other shape is not used.We might also wonder, why solid section is not used??We will discuss the reason behind selection of I beam for railway tracks in this article.

The usual, Flat Footed rails used for Broad Gauge lines is shown below with its components below.

This is typical shape of the cross-section of a track laid with Flat-footed Rails.
The Bull headed rails resemble the 'I' shape more correctly.

You might have wondered why does almost every motorcycle have its exhaust placed on the right, and not the left?It is not a design constraint as such and you can have the silencer on the left as well. But there could be many reasons otherwise.We will discuss these reasons in this article.

You might have heard about PSLV and GSLV rocket launch systems developed by the Indian Space Research Organization, or ISRO, to launch satellites into orbit.In this article we will understand the difference between PSLV and GSLV.

This is the basic difference between GSLV (Geosynchronous Satellite Launch Vehicle) and PSLV (Polar Satellite Launch Vehicle).
