Q
Explain why KM is assumed to be fixed at small angles of heel
A
- KM = KB + BM
- KB neg increase
- BM = I / V ∴ I = LB³/12▽, neg increase in B and no change in L
- GZ = GM x sinθ
KB and BM have hardly changed therefore KM is assumed to be fixed

Q
What formula to we use for the larger angles of heel?
What point is the wall sided formula effective too?
A
- Wall sided formula
- efective to θDEI
