When we roll a ball on the ground, friction plays a major role to bring the ball to halt. Calculation Example – Shear bolt connection EC3. Clamping force is determined by considering several factors including cutting force and workpiece material. COF depends on the nature of the materials and surface roughness. Equations used in the Calculation: The pressure difference between the bottom and top of an incompressible fluid column is given by the incompressible fluid statics equation, where g is the acceleration of gravity (9.81 m/s 2). The normal and friction forces are at right angles to each other. The friction factor is determined by using what is called the “Moody Diagram”. Coefficient of friction (COF) is a dimensionless number that is defined as the ratio between friction force and normal force (Eqn (2.1)). Friction pile is a kind of pile foundation. To the experienced fire protection designer, most of the information required to complete the calculation in the Darcy-Weisbach formula is familiar and self-explanatory. Thus, the total force acting down is equal to the weight of the block of soil held between the piles, plus the shear adjacent to the pile group perimeter due to negative skin friction.
