Memorize the pictures. In The Stress problems, when you find Cos(phi) and cos(theta) the denominator and numerators are found in the following way: That’s the hard stuff. The rest is just plug and chug eqations and stuff you already know. I love you and I know you’ll do fine. FCC THETA : Numerator -(dot product of the slip direction and the the stress axis) Denominator - multiply the absolute value of the two from the top together**remembering there length. (aka remember to multiply the bottom by 2) PHI : Numerator -Stress axis and the normal to the slip plane (which has the same indices as the slip plane) Denominator -multpily the two from the numerator **remember there length (multiply by sqrt(2) xsqrt(3) THETA : Numerator -(dot product of the slip direction and the stess axis)
