Re: Pier for 1100GTO #Guiding
Something to keep in mind is that deflection of a pipe with an end load is equal to F*L^3/(E * D_o^3 * Delta_D), where F is the applied force, E is the modulus of elasticity, L is the length of the pipe, D_o is the outer diameter, and Delta_D is the thickness of the pipe wall (assuming the pipe wall thickness is much smaller than the diameter of the pipe). This means that in general diameter of the pipe has a bigger impact on stiffness than thickness of the pipe wall.
For example, an 8in schedule 40 pipe of a given length will deflect 3 times less than a 5in schedule 80 pipe of the same length, made of the same material. Other considerations (for example weight) may drive towards narrower pipes.
