1. The problem statement, all variables and given/known data 2. Relevant equations ∑MA = 0, where A is the pin. Tx = Tcos150 Ty = Tsin150 3. The attempt at a solution I've drawn in the 100kN force of the beam's weight, and identified that ∑MA = 0. I attempted to find the moment arm, but really wasn't sure how do to it, or if it would even help. I'm a first year engineering student who's struggling with statics. Any help is appreciated, but please do your best to keep it as easy to understand as possible.
