DOF stands for Degrees of Freedom. It refers to the number of independent parameters that define the configuration of an object.

• DOF is the number of ways a rigid body can move in 3D space.

• For a rigid body in 3D space, there are 6 degrees of freedom - 3 translational and 3 rotational.

• Examples of DOF include linear motion along x, y, z axes and rotational motion around x, y, z axes.

Remastering in plastics is the process of improving the quality of recycled plastic materials.

• It involves adding new additives to the recycled plastic to enhance its properties.

• The process can also involve removing impurities and contaminants from the recycled plastic.

• Remastering helps to increase the value and usability of recycled plastic materials.

• Examples of remastered plastics include PET bottles, HDPE containers, and PVC pipes.

Stress-strain curve shows relationship between stress and strain in a material under tension.

• Stress-strain curve is a graphical representation of how a material deforms under stress.

• It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• Example: Steel has a high yield strength, so its stress-strain curve shows a steep initial slope.

• Example: Rubber has a low yield strength, so its stress-strain curve shows a more gradual slop...read more
