Workshop reviewers for mechanical engineering, Study notes of Mechanical Engineering

A workshop reviewer is responsible for evaluating and providing feedback on workshop proposals, submissions, or presentations. Their role typically includes: Assessment of Content: Evaluating the relevance, quality, and originality of the content presented in the workshop. Clarity and Organization: Ensuring the workshop is well-structured, clearly presented, and easy to follow. Relevance to Audience: Assessing whether the workshop is suitable and valuable for the intended audience. Quality of Materials: Reviewing any supplementary materials for accuracy and usefulness. Feedback and Recommendations: Providing constructive feedback to the presenters and suggestions for improvement. The goal of a workshop reviewer is to maintain high standards and ensure the workshops are beneficial for participants

Lecture B-SAFETY AT WORK
How often do workplace accidents occur?
-Yearly, over 3 million injuries occur in the workplace.
-5,000 deaths each year in the workplace.
Who is injured most often at work?
-Workers between the ages 15-25
-One million end up in the emergency center each year.
-An average, 600 die from fatal work injuries annually.
Why are younger workers injured at work more often than older workers?
-Lack experience or proper training.
-May be less likely to speak up or ask questions.
-Tend to take more risks.
-Perform more physical and/or dangerous jobs.
What are the common types of workplace accidents?
-Slips, trips, and falls.
-Head injuries and broken bones are common with slips, trips, and falls.
-There are estimated to be 25,000 slips, trips, and falls each day at work.
-They accounted for 25 percent of all workplace injuries. And 15 percent of all workplace
deaths.
If a person falls on their head from only three feet high, it will cause injuries similar to running
as fast as you can into a brick wall = deadly

  • 5,000 deaths each year in the workplace. Who is injured most often at work? -Workers between the ages 15-
  • One million end up in the emergency center each year. -An average, 600 die from fatal work injuries annually. Why are younger workers injured at work more often than older workers? -Lack experience or proper training. -May be less likely to speak up or ask questions. -Tend to take more risks. -Perform more physical and/or dangerous jobs. What are the common types of workplace accidents? -Slips, trips, and falls. -Head injuries and broken bones are common with slips, trips, and falls. -There are estimated to be 25,000 slips, trips, and falls each day at work. -They accounted for 25 percent of all workplace injuries. And 15 percent of all workplace deaths. If a person falls on their head from only three feet high , it will cause injuries similar to running as fast as you can into a brick wall = deadly What are the five most common causes of workplace accidents?
  1. Laziness - taking shortcuts(potential disaster)
  2. Being distracted or tired - needs 100 percent of focus(unnecessary danger)
  3. Alcohol and drug abuse - 40% of fatalities, slow a worker's reaction time, 100% of your capabilites
  4. Overconfidence - invincible, especially younger workers
  5. Ignoring safety procedures or rules - leads to someone getting hurt or killed What links the different causes of most all accidents at work?
  • Lack of awareness and focus Topic 2 - disregard Topic 3 Lecture A- Tools Vocabulary
  • There are many different shapes/sections of files, some are next. They are used for a variety of types of work. Files are classified according to their length, section / shape and cut (tooth shape).
  • HAND FILE : Used for general filing of metals such as steel. They are rectangular in section and are the most common type of file used in workshops.
  • HALF ROUND FILE : Used for filing curved surfaces. A normal hand file with its flat cutting edges is unsuitable for filing curved surfaces. However, the half round file has a curved surface which is especially useful for filing internal curves.
  • THREE SQUARE FILE : Is triangular in section and very useful when filing 'tight' corners / angles. The sharp edges allow the file to fit into corners when filing.
  • KNIFE FILE : Knife files are very useful when filing where there is little space. Knife files are very thin and can fit into small gaps.
  • SQUARE FILE: The square file is quite thin and fits into corners well. They can be used to file slots in metal or for filing where there is little space. Files are often graded according to the roughness / smoothness of the cut. The file that has the least harsh teeth is graded as 'very smooth'. The most abrasive of files is graded as 'rough'.

Topic 5 Lecture A-How to use Hacksaw

  • The hacksaw is used to cut steel and other metals. It can also be used to cut plastics , although it is not normally used to cut wood. It is sometimes called an adjustable hacksaw , because the length of the frame can be altered to hold blades of different sizes. Blades are supplied in two lengths , 250mm and 300mm. If the adjusting screw is unscrewed, the frame can be pushed into the handle, so that the smaller blades fit the hacksaw.
  • Blades are also described by the number of teeth per inch ( TPI ). Blades have 14 , 18 , 24 , 32 teeth per 25mm ( inch ). A blade with 14 TPI is coarse whilst a blade with 32 TPI is very fine.
  • Blades eventually wear or break and need replacing. The blade can be replaced by loosening the wing nut adjuster, until it comes off the two 'studs' that normally hold it in tension in the frame. A blade should always be positioned with its teeth pointing away from the handle.
  • Two types of hacksaw blade are generally available. High Carbon Steel blades are used for general cutting/sawing. They do not last as long as High Speed Steel blades. These are much more expensive , but keep their cutting edge for longer and are suitable for cutting hard materials such as stainless steel and alloys.
  • Selecting the correct number of teeth per inch (25mm) is also important. The general rule is that at least three teeth should extend across the surface of the material to be cut.
  • The material should be carefully marked out. This normally involves using an engineer's try square and scriber.

What is a hacksaw?

  • It's a type of saw that is designed for cutting metal, plastic , or other materials.
  • One of the most versatile and indispensable tools in any tool kit.
  • It's called a "hacksaw" because it's used for "hacking" through these materials , cutting them into smaller pieces.
  • The blade is made of high-carbon steel and is designed to be sharp and durable , making it perfect for cutting through tough materials. Why is the hacksaw such a great tool to have?
  • It’s relatively inexpensive and easy to use , making it a great tool for DIY projects.
  • It’s also lightweight and compact, making it easy to store and transport , and it’s versatile, allowing you to cut a variety of materials with ease to store and transport. Topic 6 Lecture A-Hammer and their uses Sledgehammer
  • 3 main parts: handle, head, and striking face
  • A sledgehammer is a unique tool that is often used to break apart slabs of concrete & breaks .It can be used to destroy nearly anything that you put in its way. Ball-peen hammer
  • 4 main parts: handle, head, Ball-peen and striking face
  • Ball peen hammers are mainly for metalwork. This tool is used to drive punches and cold chisels , set rivets, and shape metal.
  • punching on leathe r
  • setting rivet Claw hammer
  • 4 main parts: handle , head, striking face and claw (splits in the middle forming a “V” shape)
  • The claw part of the hammer is most commonly used for extracting nails from wood. The rounded end of the claw, in combination with the handle, is used to gain leverage when extracting a nail. Mallet hammer
  • 3 main parts: handle , head , and striking face
  • Mallets are usually used in carpentry to knock wooden pieces together. A mallet will not deform the striking surface of the workpiece (hear wood), as most metal hammers would.
  • Replacement of the tips are as easy as prying off the old tip and popping on the new one. Machinist hammer
  • 4 main parts: handle , head , Peen face and striking face
  • The main striking face is large and dense while the rear side tends to be pointed. The purpose of the pointed end is to concentrate all the force from the hammer to a smaller area and amplify the impact.
  • A machinist's hammer is used by blacksmiths to hammer red-hot metal for shaping or by machinists to join or align metal parts together. Topic 7
