Q: Figure 2 shows a typical mast from a modern racing yacht. It is built in the form of a thin-walled tube (hallow cylinder). To win long-haul ocean races, these yachts need to have every advantage that high-performance materials can give, in terms of maximum stiffness (must not easily deflect), plus minimum weight as possible. The following are the equations to use: 1(F13 8 == 8 EI and I = ar³t, A = 2art assume l and cross section are fixed but thickness t is free to change. • Drive the performance index for this problem • Use table 1 to select top three materials with the best performance index.

A plate with a center hole is subjected to both of axial force (F) and bending moment (M; acting about weak axis). Predict the fatigue failure with 50% reliability. The plate is machined from alloy steel (S.= 470 MPa and Sy= 350 MPa).

2. The Goodman diagram relates oa and Om for fatigue failure after a specific number of cycles Nf, where da is the cyclic stress amplitude, and om the mean stress. For a steel specimen it is found that oa = a (0).[1- (om/OTS)] where OTS is the metal's tensile stress (375MPa), and a (0)~0.450TS is the 10' cycle fatigue limit at zero mean stress. Assuming the specimen is cycled repeatedly between 0 stress and a peak stress, what is the maximum peak stress if failure in < 107 cycles is to be avoided?
