The shear modulus is concerned with the deformation of a solid when it experiences a force parallel to one of its surfaces while its opposite face experiences an opposing force (such as friction). In the case of an object shaped like a rectangular prism, it will deform into a parallelepiped.
Nylon MD –(Molybdenum di-sulfide lubricant MoS2), lowers surface friction and increases surface hardness, strength and stiffness. Nylon Oil filled – oil filled grade lowers surface friction and hardness, increases impact resistance Nylon 6/6 GF30 – 30 % glass filled has higher strength, stiffness and temperature resistance.
The coefficient of friction is a number which represents the friction between two surfaces. Between two equal surfaces, the coefficient of friction will be the same. The symbol usually used for the coefficient of friction is m. The maximum frictional force (when a body is sliding or is in limiting equilibrium) is equal to the coefficient of .
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur.Its chemical formula is MoS 2.. The compound is classified as a transition metal dichalcogenide.It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. MoS 2 is relatively unreactive. It is unaffected by dilute acids and oxygen.

Static friction is the force needed to create movement between two surfaces. The coefficient of friction is a critical property of all materials which run on high speed manufacturing lines; particularly those in the printing and packaging industry. Coefficient of friction is routinely specified for plastic flowrapping films.
Gravity and Air Resistance. Most objects falling through air experience a type of fluid friction called air resistance. Air resistance is not the same for all objects. The greater the surface area of the object the greater the air resistance. However, since the elephant has more mass, it has more downward force of gravity and falls faster.

The characters of PA66 are good elasticity, wear resistance, good self-lubricating properties, oil resistance, good chemical stability and the advantage of excellent processing fluidity [12,13]. If PP and PA66 can be welded together by laser, their respective advantages will be fully utilized and they will have great application prospects.
Dynamic friction resistance occurs when a material is sliding or in rotary motion, presenting conspicuous variations due to the hardness, the surface roughness of the mating material, the pressure between mating materials, the friction rate, the presence and type of lubricants between mating surfaces, the temperature, contamination, and moisture.
