Method of Projections tell us the positions of the views where they are projecting on the Planes. Consider 1st Angle of projection, All the views from a particular direction are projected on the opposite side, while in 3rd Angle of projection, All the views from a particular direction are projected on the same side. Take a case of 2nd Angle of Projections( means object lies in 2nd Quadrant) since the image is to be formed on the planes only that is why we have to keep right side view on the same side from viewing while top view on the opposite side from viewing. This contradicts view placement( i.e. once you are placing on same side and once on Opposite). Same is applicable in 4th Angle of Projection also.

How Do you calculate the area of pipe?
Start with the maximum flow speed (metres per second) for your liquid, then mutiply by the area of the pipe in square metres, the result is maximum volume flow rate in cubic metres per second.
What does an architect use?
They use mostly their head (imagination) then use pencil and paper to draw and refine their ideas. They also use computers to 'draw' their designs in 2D and 3D.
How do you construct a cyclone resistant buildings?
Choose the location carefully to avoid the full force of the wind or flood Use building layout with a simple regular shape, to avoid concentration of pressure. Build the roof at an angle of 30° to 45° to prevent it being lifted off by the wind. Avoid wide roof overhangs; separate the veranda structure from the house. Make sure the foundations, walls, and roof structure are all firmly fixed together. Reinforce the bracing in the structure; strengthen walls and joints/ junctions to increase stiffness. Make sure the roof covering is firmly attached to the roof structure to prevent it from lifting. If doors & shutters cannot be shut, make sure there are opposing openings to reduce pressure build up. Use doors and shutters that can be closed. Plant trees around the house as wind breaks and reduce flow of water, but not too close.
Are excavator can be use for lifting?
yes
What is the use of a flat roof?
Drying peppers.
When you do not use second and fourth angle projection in AutoCAD?
you do not use it when you multiply
Why can not use second angle and four angle projection method in Engineering drawing?
Because in second angle both quaderent comes negative that's why we cant use second angle method
Why projection not use second and fourth angle in mechanical drawing?
Second and fourth angle projections are not commonly used in mechanical drawing because they can lead to confusion and misinterpretation of the object's geometry. In the first angle projection, the object is placed in the first quadrant, which aligns with how engineers and manufacturers typically visualize the part in relation to its views. The third angle projection, which is the most widely used, presents views in a more intuitive manner, allowing for clearer communication of dimensions and features. Therefore, the first and third angles are preferred for their clarity and consistency in representing 3D objects in 2D space.
Why indian use first angle projection method?
they are fools
Why can not we use second angle projection method in Engineering drawing?
In 1st angle projection the front view will be in the top of the xy plane and the top view will be in the bottom of the xy plane .In 3rd angle projection the top view will be in the top of the xy plane and front view will be in bottom of the xy plane. dis will give a clear view.i hope u know dis... but in 2 angle projection both the views(front and top) will be in the top of the xy plane and in 4th angle projection both the views (front and top) will be in the bottom of the xy plane... since both the views will be in one side of the xy plane, its not possible to draw... both views will merge... to get more clear view, refer any basic engineering drawing book.......
Advantages of a third angle drawing?
Third angle projection is in common use in the USA, Canada, and the UK. The rest of the world more commonly uses first angle. There is no inherent superiority of one projection over the other. When you are making drawings that may be used internationally, it's a very good idea to indicate by a small symbolic diagram which projection is in use. This diagram is usually a side and end view of a truncated cone.
How do you find the first angle and the second angle of a triangle?
use a protractor
Why you only use cosine for scalar product?
That is how the scalar product is defined. Also, the projection of one vector onto another at an angle to it is directly proportional to the cosine of that angle.
How do you astro project?
First of all, it's ASTRAL projection. and second, there must be a better use of your time.
What countries use 1st or 3rd Angle Projections?
First Angle Projection is primarily used in countries such as India, Australia, and most of Europe, while Third Angle Projection is favored in the United States, Canada, and some parts of Asia. The choice between these two methods often reflects regional standards in engineering and technical drawings. Each projection method differs in how objects are represented on a two-dimensional plane, influencing how designs are interpreted and communicated.
What measures 1 fourth of an angle?
Well, honey, if you're talking about a circle, then a quarter of an angle would be 90 degrees. That's because a full circle has 360 degrees, so a quarter would be a nice and neat 90 degrees. So, there you have it, a fourth of an angle measures 90 degrees.
Why we use sine angle in cross product while cos angle in dot product?
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin
