What type of bonding occurs in polymers? covalent bonds How does the structure of a polymer affect its properties? Polymers consist of very long molecules that contain chains of carbon. They too are held together by very strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules. This […]

Why is reliability important in system design?
Why is reliability important in system design? Design for reliability ensures that products and systems perform a specified function within a given environment for an expected lifecycle. DfR often occurs at the design stage — before physical prototyping — and is often part of an overall design for excellence (DfX) strategy. What is reliability in […]
How are tolerances shown on an engineering drawing?
How are tolerances shown on an engineering drawing? Tolerance is the total amount a dimension may vary and is the difference between the maximum and minimum limits. Tolerances are represented as Tolerance Values (A) or as Direct Limits (B). Nominal Size is used to describe the general size of a part. Actual Size is the […]
