Using Torque Wrenches
Most torque wrenches are required to be set at “0”when not in use to maintain calibration.
Please refer to the manufacturer’s instructions for further information on use and maintenance.
Setting Torque Value on a Dial Indicator Wrench:
1. Make sure your indicator needle is set to “0” [..].
Adjust torque wrench
Which torque wrench?
First you need to choose a torque wrench suitable for your needs. Let’s take a bike for example and we need to adjust my drive chain.
We can choose a cheap torque wrench like Halfords, that have a good quality and are accurate enough for most jobs.
We will also need a socket to fit each of the jobs, they are interchangeable with some socket sets [..]
Dial Torque Wrench
What unit of measurements is read on a dial torque wrench ?
The unit of measurements on a dial torque wrench is either foot pounds (usual on large wrenches), inch pounds (usual on smaller 3/8″ drive wrenches) or Newton/Meters (metric, either size). Some will have readouts for both ASE and Metric [..] .
Torque socket wrench
What is the Difference between a torque wrench and a socket wrench ?
A socket wrench is like a small steel tube – one end has ridges that fit precisely around a bolt. The other end often has an opening of 1/4″, 3/8″, or 1/2″ square. This end receives the protruded part of a ratchet with the same dimension.
Most torque wrenches look like a larger version of a ratchet[..]
Torque Arm | What is it | Who did you find it ?
Torque arm is the distance from the center of the axis to the point of the applied force.
It’s expressed in either in foot or inch pounds, in the imperial system.
The torque arm is often referred as force arm, lever arm, or moment arm.
In a lever, the moment (torque) arm of the force is often referred to as the force arm and that of the resistance is referred [..]
Convert a torque wrench from inch pounds to foot pounds
If you need to torque something let’s say to 16 Ft pounds, you can use also a torque wrench that measures “inch” pounds. So, how do I convert that ?
It is a simple its a simple math conversion. A foot pound is the torque you get when you apply a pound of force on the end of a 1 foot rod. So 1 ft*lb = 12 in*lbs.
Simply multiply your [..]
Computer security
What is computer security?
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, [..]
Wireless Phones
What are wireless phones?
Wireless telephones are hand-held phones with built-in antennas, often called cell, mobile, or PCS phones.
How do they Work?
When you talk into a wireless telephone, it picks up your voice and converts the sound to radiofrequency energy (or radio waves). The radio waves travel through the air until they reach a receiver at a nearby base station. The base station then sends your call through the telephone network [..]
Security – Principles of Authentification
The broadest definition of authentication within computing systems encompasses identity verification, message origin authentication, and message content authentication.
The concept of identity verification specifically applies to principals with information processing and decision making capabilities, including human users, computing systems and processes executing on those systems. From an authentication standpoint, the term “user” applies to all these principals. This guideline focuses on technology and techniques for verifying the identity of human users [..]
Electronic Credentials
Paper credentials are documents that attest to the identity or other attributes of an individual or entity called the subject of the credentials. Some common paper credentials include passports, birth certificates, driver’s licenses, and employee identity cards.
The credentials themselves are authenticated in a variety of ways: traditionally perhaps by a signature or a seal, special papers and inks, high quality engraving, and today by more complex mechanisms, such as [..]
