Factor of Safety Calculations Continued...
Solve Equation 2.35
beta = ARCTAN[Ci/(C2`C3 + C4)] = ARCTAN[0.9989/(9.3397'0 + 0.046)] = 1.5248 radians
Calculate Algebraic Constants for Equation 2.38
C1 = M/N + SIN(lambda + beta) = 1.942 + SIN(0.046 + 1.5248) = 2.942
C2 = M/N + 1 = 1.942 + 1 = 2.942
Solve Equation 2.38
eta' = eta(C1/C2) = 0.315(2.942/2.942) = 0.315
Calculate Algebraic Constants for Equation 2.34
C1 = (L2/L1)COS(theta) _ (0.971/0.312)COS(0) = 3.1122
C2 = SIN(theta)COS(beta) = SIN(0)COS(1.5248) = 0
C3 = (L2/L1)eta' _ (0.971/0.312)0.315 = 0.9803
C4 = (L3/L1)(Fd'/VVS) _(0.5/0.312)(17.05/60.6) = 0.4509
C5 = SIN(lambda + beta) = SIN(0.046 + 1.5248) = 1
C6 = (L4/L1)(FI'/VVS) _(0.971/0.312)(17.05/60.6) = 0.8756
Solve Equation 2.34
SF = C1/[C2 + C3 + (C4)(CS) + C6] = 3.1122/[0 + 0.9803 +(0.4509)(1) + 0.8756] = 1.35
