    What are the coordinate direction angles for the resultant couple moment?

    It wants alpha as the angle between the moment axis and the x axis, and beta as the angle between the moment axis and the y axis. I have tried inputting the following: \alpha = 121, \beta = 31 \alpha = 149, \beta = 31 \alpha = 31, \beta = 59 \alpha = 59, \beta = 31 With no success. Given the...
