Q1: What parameters should be kept in mind while designing a machine?
Ans:
The following parameters should be considered while designing a machine:- ➔ Strength of the material
- ➔ Safety and reliability
- ➔ Cost of production
- ➔ Ease of manufacturing
- ➔ Efficiency of the machine
- ➔ Maintenance and durability
Q2: What is Rectilinear Motion?
Ans: Rectilinear motion is the motion of a body along a straight line.
In this type of motion, the direction of movement remains the same and the path followed by the object is straight.
Q3: What is Curvilinear Motion?
Ans: Curvilinear motion is the motion of a body along a curved path.
In this motion, the direction of movement continuously changes because the object follows a curved path.
Q4: What is the Factor of Safety while designing a machine?
Ans: The Factor of Safety (FOS) is the ratio of the maximum stress that a material can withstand to the actual working stress applied on it.
It ensures that the machine operates safely without failure.
Formula:
Factor of Safety = Maximum Stress / Working Stress
Q5: Name the types of Machine Designing.
Ans:
Following are the types of Machine Designing:- ➔ Adaptive Design
- ➔ Development Design
- ➔ New Design
Q6: What is Adaptive Design in Machine Designing?
Ans: Adaptive design is the process of making small changes or improvements in an existing machine design to meet new requirements.
It does not create a completely new machine but modifies the existing one.
Q7: What is Development Design in Machine Designing?
Ans: Development design means improving an existing machine by applying new ideas, better materials, or advanced technology.
It increases the performance and efficiency of the machine.
Q8: What is New Design in Machine Designing?
Ans: New design refers to the creation of a completely new machine or product that has not existed before.
It requires detailed research, creativity, and engineering analysis.
Q9: What is Brainstorming? How is it done for machine designing?
Ans: Brainstorming is a creative process in which a group of people share and discuss different ideas to solve a problem or develop a new design.
In machine designing, engineers discuss many possible ideas, analyze them, and select the best solution for developing the machine.
Q10: What is a Prototype?
Ans: A prototype is the first working model of a machine or product.
It is built to test the design, check performance, and identify any problems before final production.
Q11: Name the stages of design methods for Machine Designing.
Ans:
The design methods in machine design include the following stages:- ➔ Identify the need
- ➔ Select possible mechanism
- ➔ Analysis of forces
- ➔ Selection of materials
- ➔ Design of elements
- ➔ Modifications
- ➔ Detailed Drawings
- ➔ Production
- ➔ Quality Check
Q12: Name the stages of Design Product Concept.
Ans:
The Design Product Concept includes five stages, which are as follows:- ➔ Research
- ➔ Defining
- ➔ Brainstorming
- ➔ Prototype
- ➔ Testing
