the coefficient of static friction between two surfaces depends upon
Friction For surfaces at rest relative to each other   μ = μ  s    {\displaystyle \mu =\mu _{\mathrm {s} }\,} , where   μ  s    {\displaystyle \mu _{\mathrm {s} }\,}  is the coefficient of static friction. This is usually larger than its kinetic counterpart. The coefficient of static friction exhibited by a pair of contacting surfaces depends upon the combined effects of material deformation characteristics and surface roughness, both of which have their origins in the chemical bonding between atoms in each of the bulk materials and between the material surfaces and any adsorbed material. The fractality of surfaces, a parameter describing the scaling behavior of surface asperities, is known to play an important role in determining the magnitude of the static friction.[1]
Mechanical joint This is used to connect rigidly two rods which transmit motion in the axial direction, without rotation. These joints may be subjected to tensile or compressive forces along the axes of the rods.

Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
