Engineering Design of Shaft, Key and Coupling

Hello Dear Students,

Engineering design is the method that engineers use to identify and solve problems. It has been described and mapped out in many ways, but all descriptions include some common attributes:

Engineering design is a process. This powerful approach to problem solving is flexible enough to work in almost any situation. Engineers learn important information about both the problem and possible solutions at each step or phase of the process.

You will learn in this course

• Definition of Shaft

• Material of Shaft

• Properties of Shaft Material

• Design of shaft subjected to twisting moments

• Design of shaft subjected to Bending moments

• Design of Sunk Key

• Design of sleeve or muff coupling

  
  

  Learning Objectives

  After this activity, students should be able to:

  • Identify the need for a specific engineering design project.

  • Describe the design project context.

  • Identify and differentiate the design project constraints and requirements.

Engineering design is a process. It involves tools and ways of thinking that people can use in almost any situation. Each part of the process reveals information about the problem and possible solutions.

Engineering design is iterative. Engineers are expected to repeat the process. Steps like defining, planning, modeling, and testing, can be completed in different sequences to find the best possible solution.

Engineering design is problem-solving. It always has a purpose that is specific and known. It may involve experiments to better understand the problem (or a possible solution), but the goal of engineering design is always to solve a problem.

Engineering design is finding the best solution. Evaluation is an important part of the process. Solutions have different strengths and weaknesses and have to stay within the physical limits of available time, cost, tools, and resources.
