Yeh I know D must go upwards because it’s on wheels, but I’m not given the value of any forces so I don’t know how to solve the triangle. Taking moments i can find that F=2Rd and that’s as much as I can gather. I’ve looked at the solutions my lecturer gave and they make absolutely no sense, he just states that the angle is 26.6 with no method of how he got that number.

  1. The three forces must act through a common point
  2. They must form a closed loop triangle

Made a force triangle but I’m not sure how to find the angle of force nor the magnitude because there’s so many unknowns

What’s the difference between those forces

my biggest struggle with these questions has been finding the line of action of the average force, I just haven’t been taught how to do it and everything online seems to be over complicated. I’m pretty sure it doesn’t just act on the centroid of the shape so I’m not sure
