Rule of tension and compression
WebbWell, if you have 3 ropes, it could just be that 2 ropes are holding the weight, and the third is hanging slack, because it is too long. If you assume, that the ropes have the right length, that they are all under tension, or if you replace the ropes with bars (they support both tension and compression), it is solveable, but it gets complicated. btw this is called a … Webb6 mars 2024 · If the magnitudes of a calculated force is positive and it is pointing away from the joint, you have tension. If it is negative and pointing away from the joint you have compression. You only have one unknown vertical force, CL. Its value and therefore …

WebbIf the material even, then the tensile and compression properties and behavior is the same. On the other hand, if the material is uneven , it will have different compressive and tensile properties. Webb28 okt. 2024 · Two of the most common types of stress and strain are tensile and compressive stress and strain. Tensile means there is an increase in length of the object, and compressive is a decrease in length.
