Dermining moments caused in tension of cable

In summary, the moment created about the support leg at "A" caused by the tension in the cable of 12.3kN can be determined by multiplying the force magnitude (12.3 kN) by the perpendicular distance between the force vector and the point in question. Alternatively, the vector can be resolved into x and y components, and the moment is equal to the sum of each component multiplied by its respective x and y distance from the point.

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.
 

Related to Dermining moments caused in tension of cable

1. What is meant by "dermining moments" in relation to tension of cables?

Dermining moments refer to the forces acting on a cable that cause it to bend or twist. These moments are caused by the tension applied to the cable and can affect its structural integrity.

2. How does tension in a cable lead to dermining moments?

When a cable is under tension, the force is not evenly distributed along its length. This uneven distribution of forces can cause the cable to bend or twist, resulting in dermining moments.

3. What factors can contribute to the formation of dermining moments in tensioned cables?

The main factors that can contribute to dermining moments in tensioned cables include the magnitude and direction of the applied tension, the length and diameter of the cable, and any external forces acting on the cable.

4. How do dermining moments affect the strength and stability of a cable?

Dermining moments can weaken the structural integrity of a cable, making it more susceptible to failure. They can also cause the cable to deform or buckle, compromising its stability and ability to support the intended load.

5. How can dermining moments be minimized or prevented in tensioned cables?

To minimize or prevent dermining moments in tensioned cables, engineers can use various techniques such as adjusting the tension distribution, using cable supports or guides, and selecting appropriate cable materials and dimensions based on the specific application and load requirements.
