Homework Statement
Hello,
I am looking to determine the moment of inertia for the cantilever beam pictured below. I want I to be a function of L1 and T1.
Known variables: L, D, P, t
Dependent variables: T2, L2
Design variables: T1, L1
Homework Equations
L2 = L - L1
T2 = T1 - t
Standard Moment of Inertia: I = π/4 * (Ro^4 - Ri^4)
I am looking to modify the above equation to be include 2 sections of variable thickness
The Attempt at a Solution
I1 = π/64 * (D^4 - (D - T1)^4)
I = I1 * (1 - L1/L)^4
The above solution is valid for a linearly tapered beam, not a beam with 2 discrete sections. I have not been able to find any derived moments of inertia for the above shape. Any help would be greatly appreciated!
