Material selection
When we want to make something, we need to choose what we want to make it out of. This is called material selection.
For example, if we wanted to make a chair, we could use wood, metal, plastic, or even recycled materials. We have to think about what we want the chair to do, how strong it needs to be, and how it will be used.
Each material has its own strengths and weaknesses. Wood is good for making things that need to look nice, but may not be as strong as metal. Metal can be very strong but is heavy and may rust if it gets wet. Plastic is lightweight and durable, but may not last as long as other materials.
We also have to think about how much it costs to make our object. Some materials are expensive, while others are very cheap. This can affect how we make our material selection.
So, when we want to make something, we have to think about what we want it to do, how we will use it, and how it will look. Then we choose the best material to make it from based on these factors.
