Dermining moments caused in tension of cable

AI Thread Summary
To determine the moment about support leg "A" caused by the 12.3 kN tension in the cable, one must calculate the moment using the force magnitude multiplied by the perpendicular distance from the force vector to point "A." Alternatively, resolving the tension into x and y components allows for calculating the moment by summing each component's contribution based on its respective distance from point "A." The forum emphasizes the importance of showing an initial attempt at the solution before receiving further assistance. This approach ensures a better understanding of the underlying principles involved in calculating moments. Engaging with the problem actively is encouraged for effective learning.

Reaching back many years in memory...
moment due to a force vector is the force magnitude (12.3 kN) times the perpendicular distance between the force vector & the point in question. Or resolve the vector into x & y components, the moments is the sum of each component times its respective x & y distance from point.

Welcome to the PF, jmohle. On schoolwork questions, the PF rules require you to post your own attempt at a solution before we can offer tutorial help. So please write out the equations that Carl is alluding to, and see how far you can get.
