How to Determine the Moment About Reaction D and Smallest Force at Point B – Moment Problem 8

In this video, we calculate the angle of the force due to the moment about a point by summation of moments. This problem is solved by using static moment calculations about a point where moment equals a force times a perpendicular distance.
