Quick question, why is the perpendicular distance the cos30 side and not sin30 side . I am asking because the force is moving the block a distance of sin 30?
FYI :
I really do enjoy your lectures, the concepts and examples are put in a very understandable and intuitive context.

Hello, could I not have used L/2sin*theta? I used it and it also gotten me to 86.6 Nm.
