WebConsider 2 steel wires being stretched by the same weight. One wire is double the length of the other. They have the same cross-sectional area, and the forces are the same but the extensions are not - the longer wire stretches twice as much even though it has the same tensile stress because it is twice as long to start with. WebJun 15, 2024 · A steel wire is loaded by 2 kg weight. If the radius of the wire is doubled, then its extension will become (a) half (b) four times (c) one-fourth (d) double Answer Question 6. A cable breaks if stretched by more than 2 mm. It is cut into two equal parts. By how much either part can be stretched without breaking? (a) 2mm (b) 1 mm (c) 0.5 mm

Due to the nature of a self-weighting cable; it will have a minimum force at the bottom of the cable. The bottom of the cable isn't being stretched, because there is no weight below it pulling it down. dandy salon gift certificatesWebThe hanging cable derivation arises from analyzing it in the sense of a physical problem. The only forces acting on a hanging cable at a certain point are its weight and the tension in the cable. The resultant of these forces must equal to zero considering the cable is at rest. By knowing their sum a differential equation arises birmingham dentistry interviewWebConsider standing waves in a stretched wire experiment: How might the tension in a string be not equal to the weight of the hanging mass?
