Hello to everyone, merry christmas and happy new year! I was trying some exercises on the Feynman Lectures, on the topic of statics, and I came across with a problem which, simplified until where I am stuck, asks for the tension of a cable perpendicular to a bar with a weight on the top of it, as in the picture below. I don't know which trigonometrical function should I use, as the force going downwards y-axis is perpendicular to the tension on the x-axis, the tension seems to be 0! (That is obviously incorrect) Should I first calculate the force going down the bar, and then multiply it by the angle θ?
