## How is a rectangle and square the same?

Definition: A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.

## How do you make a square stronger?

Just by adding diagonal beam through the middle of a square you are effectively turning the structure into two triangles and eventually making it stronger.

## Why is triangle the strongest polygon?

In a nutshell, triangles are the strongest polygon because their sides are rigid. This means that if pressure is applied to a triangle, the sides stay…

## Why are rectangles weak?

The rectangle is a wobbly, unstable shape. When you push the side, it flops into a slanted parallelogram. This happens without any of the rectangle’s sides changing length. Now when you push the side, the diagonal brace gets squeezed, preventing the rectangle from flopping over.

## How strong is an arc?

The E70s6 bare wire used in MIG and 7018 ARC used in Arc welders are both equally strong. They have a 70,000 psi tensile strength, which is stronger than most steels that you will work with.

## What’s the hardest type of welding?

Tungsten Inert Gas

## Is ARC or MIG easier?

With MIG welding it’s much easier to start and maintain the arc so the process will be much smoother with fewer stops and starts. Plus you can MIG weld with one hand as you just need to hold the trigger on the MIG gun. The downside is that the setup is more complex.

## What is the hardest metal to weld?

Aluminum Skill Level

## Is stick welding the easiest?

For a beginner, stick welding is also more difficult to learn and use. The ability to strike and maintain an arc is particularly difficult but once you learn how to do it, things become much easier. Currently, stick welders are available in AC, DC or AC/DC currents. Welders with AC input are the most economical.

## Is gasless MIG welding any good?

Most non-industrial gas MIG welders are capable of welding metal up to ¼” thick. On the other hand, gasless MIG welders have better penetration, making them much more suitable for welding thicker metal with good results. They are also more efficient and have higher productivity than gas MIG welders.

## Is stick welding stronger than MIG?

Stick welding is slightly stronger and better because of its ability to carry out substantial welding projects. Stick can also penetrate more than MIG welding.

## Is flux core welding as strong as MIG?

​Looking At MIG Welding Metal Penetration V Flux Core. Flux core welding has the reputation of better metal penetration than MIG welding.

## What is the easiest type of welding to learn?

gas metal arc welding

## Can I run a welder at home?

A welder such as a Millermatic 141 MIG welder is typically able to handle most household projects, but some welders prefer to use a 220V welder at home so that they can weld thicker steel on heavy-duty projects and achieve sufficient heat to create a strong weld.

## What type of welder should a beginner use?

MIG Welding (Beginner) MIG welders are among the best type for beginners, as they’re designed with a wire welding electrode on a spool that is fed at a pre-selected speed through a welding gun. As a semi-automatic or automatic process, gas metal arc welding (GMAW or MIG), is the easiest to learn.
