WebApr 25, 2024 · What you may be remembering is that, in a static situation, the total force on the cable must be zero because it is not moving. In the simplest situation of a cable being pulled at both ends, the tension forces at opposite ends are equal in magnitude and opposite in direction. This means that the total force on the cable is zero, not the tension. Web3.4.4 Link. A link has two hinges, one at each end. It permits movement in all direction, except in a direction parallel to its longitudinal axis, which passes through the two hinges. In other words, the reaction force of a link is in the direction of the link, along its longitudinal axis. 3.4.5 Fixed Support.

Statics forces on cables

Webup on the cable. The force of the cable pulling down on the towers is transferred to the ground through the towers and creates the reaction F ground, towershown in Figures 3.3and 3.4d. Because the tower is being pushed on at the top and bottom, it is in compression. 3. Continue tracing the main cable to the anchorage. Because the WebSupports that are commonly found in statics can be represented by stylized models called support conventions. An actual support may be a close approximation of a model. The forces and moments exerted on a rigid body by its supports are called reactions. These forces and moments are reacting to external loads that are applied to the rigid body.

Topics in Statics: … WebFeb 20, 2024 · Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pulls only parallel to its length; thus, a force carried by a flexible connector is a tension with direction parallel to the connector. It is important to understand that tension is a pull in a connector. In contrast, consider the phrase: “You can’t push a rope.”

WebAn angled force can be broken down to horizontal and vertical components (see Figure 2 below).
