### Guide to Hardware for Engineering and Industry

This guide to hardware deals with industry-standard items of which, though common, the selection of can make or break the repair, upgrade, or maintenance of essential equipment. How much do you know about the technical standards for the fasteners, bearings, belts, and seals you’re already using?

### An Engineering Guide to AC and DC Motor Designs and Operation

Most rotational applications in industry and manufacturing depend on electric motors. Our day to day life depends on electronic and electrical devices, and they, too, in turn depend on electric motors. In this guide, we look at AC and DC motor designs and operational theory.

### How to Work With Metal Studs

During some cases, metal units with complicated orientations may become difficult securing or integrating with other metal components. Metal Studs are especially made for such applications for fixing complex metal structures or assemblies firmly over desired positions.

### What is a Data Table - Examples of Data Tables in Engineering

Arranging information into orderly rows and columns is one of the most common forms of communicating precision tabular data. This article explains how tables are used in engineering, how they are created and filled, and includes two real-world examples of their use.

### Precision Turning & Tool Making in Demand: Skilled Laborers are Still Needed

How do skilled tradesmen obtain their skills? Learn how they are best employed in the modern day arena of highly automated machining, and why there will always be a need for skilled labor.

### How to Calculate First, Second and Third Pulley Systems

The article explains the three fundamental systems of pulleys, covering their operational description and methods for calculating their velocity ratio, mechanical advantage, and efficiency.

### Lesson Plan on Marking Out Tools for Metals

Marking out or scribing metals may be performed for laying out the guidelines over the job which might exactly represent the workshop drawing intended for the particular job work. This is a lesson plan on marking out tools for metal.

### Mechanical Vectors, Rotations, and Tensors

What are the differences between the vector and the tensor? What are the relation between the mechanical rotations vectors and tensors? This article will also cover these all.

### How to Use a Mechanical Drafting Machine

A mechanical drafting machine is used as a conventional method of producing an engineering drawing used in many offices and industries. A drafting machine is installed on an angular arm or beam that can be secured on the table permanently.

### Calculating Industrial Weight Lifting Machines

Moving huge weights used to be a big challenge for workers, which led to the invention of lifting machines. These well calculated, efficient mechanisms well allowed us to forge ahead into today’s modern industrial world. Let’s learn about a few of these intelligent mechanical tools.
