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

Calculating Tension and Sag in a Cable - Eng-Tips Forums
WebTension refers to the force that is transmitted through a string, rope, wire, or other similar object when it is pulled tight, trying to restore the object to its original, unstretched length. … WebA steel wire 30 ft long, hanging vertically, supports a load of 500 lb. Neglecting the weight of the wire, determine the required diameter if the stress is not to exceed 20 ksi and the total elongation is not to exceed 0.20 in. Assume E = 29 × 10 6 psi.
