Answer 1

2 = cos-1 uju2 + V1V2 + WW2 * Mu + v + 2)(x + y + w3) | (1)0) +(2)(1) + (0)(-1) 2 2 = cos- Cos 1 = 50.80 10 (1)2 + (2)2 + (0)2 (0)2 + (1)2 + (-1)]] (1)(1)+(1)(2) + (1)0 = cos -1 cos1 2 = 39,20 [2)2 + (1)2 + (1)2] [(n)2 + (2)2 + (0)2]] Therefore, the Schmid factor is equal to ( 3 )( 2 ) cos o cos 2 = cos(39.2°) cos(50.8°) = 0.490 U10) Chapter 07, Problem 7.11 Sometimes cos cos 2 in Equation 72 [120) direction parallel to the load s e d the Schmid factor.
