The moment of inertia of the section depends upon its cross-sectional (width, depth & area of material) parameters. With the Terrain Ruler module installed, Drag Ruler is able to take difficult terrain that was placed down using the Enhanced Terrain Layer or TerrainLayer module into account. Rulers are made from durable materials like wood, plastic or metal. These materials are hard wearing and are usually shatter resistant and scratch proof as they are made to last a long time. A ruler, also known as a rule, is a flat, straightedge measuring instrument with equally marked spacing etched or moulded along its length. The spacing forms a measuring scale of either metric or imperial measurements, which are usually in increments of centimetres (cm) and millimetres (mm) and inches (sometimes denoted as ") respectively. Rulers are used to measure the length of an object or its edge precisely and as a guide for drawing or scoring straight lines. Some rulers have measurements on both sides. The edges of rulers are often bevelled to reduce measurement errors. Who uses rulers? This lesson can be expanded to a second lesson looking at how the material a bridge is made out of can change its strength; see second lesson for details. Learning Objectives

Micro-fine marking holes at every scale line to instantly locate your sharp pencil point or scribe exactly on target with zero uncertainty and no eye strain!That said, whether or not this turns out to be the ruler for you, considering its uber-low price and quality, it’s definitely worth finding out! The Westcott ruler is also suitable for children and teens since the edges are rounded vs. pointy and sharp (this is one of the common disadvantages of many craft metal rulers!). And although you can use a regular ruler for certain stages of your sewing ventures, once you get into more angled, elaborate work like pattern drafting and fitting adjustments, you’ll require something a little more specific. That’s when a curved sewing ruler comes into the picture! Imagine the ruler to be made of fibers and think of a cross section to calculate the force and torque exerted by the parts of the ruler on either side of the cross section on each other through these "fibers" that run along the ruler's length, normal to the cross section. The tool’s sliding brass gauge measures up to 3.15 inches (80mm) with a graduation of 1/16 inch (1mm). While there are electric, plastic calipers available, this retro, metal model is best if you prefer more artisan hand-crafting techniques vs. modern shortcuts. Don’t get me wrong, these can be very handy too!

A ruler is a ruler, right? In part, yes. On the other hand, a metal ruler will feel different than a plastic or wooden alternative. They’re manufactured in various designs, weights, and lengths; some work like a charm across multiple surfaces, while others are a little more specialized and curated for specific purposes. This tool features a stainless steel grid that aids in speeding up the diamond placing process while ensuring more accuracy. Your set will include three different styles: 599 blank grids, 520 blank grids, and 699 blank grids to accommodate square and round drills. If you’re looking for super neat layouts, no matter if for larger or smaller canvases, this tool will give you a hand — you won’t need to constantly adjust and tweak your drills after placing them on your surface. This also means you’ll be working more efficiently and in less time.Metal rulers are some of the best additions to any craft station since they’re more resilient and versatile than their plastic and wooden counterparts. Sure, these may be cheaper, but once you have a metal ruler, it will stand the test of time, granted you maintain it properly. With guide holes at every 45º, 30º, 22.5º, 5º, 1º, and 0.5º interval, the Marking Protractor can plot any angle with ease and absolute accuracy. A metal T-Bar and see-through crosshairs provide exact alignment against the edge of your workpiece. Remove the T-Bar to work on flat surfaces or to use the 6” centering scale. FOUR angle scales: 0º left to 180º right, 180º right to 0º left, 0º top to 90º left and right, and 90º top to 0º left and right suit every need. Stainless steel is an eco-friendly material and can be recycled again and again. Metal rulers are a great option to keep crafting sustainable! Good quality metal rulers will have etched vs. printed markings. This ensures they won’t fade over time. If the thinnest part of the cross section is in the plane of bending, then none of these fibres are very far from the neutral axis. They therefore cannot exert very much torque for a given tension / compression, so the cross section cannot withstand bending very well and is thus "flimsy".

Last up is one of the most innovative takes on metal rulers, this time for diamond painting! Again, this is not your traditional ruler with numbered markings, but instead, a specifically designed stainless steel ruler for 5D art.

INCRA's Precision Bend Rule offers unparalleled accuracy, having patented marking holes to mark in rather than just etched graduations, these Rules allow you to mark out precisely with no risk of error. The most important thing to know is what you need to get the job done, depending on your craft, skill level, and budget. Leatherworking is one of the oldest art forms, and while still viewed as a somewhat niche creative hobby, it has resurfaced in recent years thanks to the offer of accessible leather crafting kits and toolsets. Stainless steel metal rulers are more durable than plastic or wooden models. Plus, no splinters! On the other hand, they will require some level of maintenance to enhance longevity. The neutral axis depth for a symmetrical section will be at its half depth, considering the major axis.
