(chatquestion)...in N/m2 will be 2.0 X lo NIm2. Its Young's modulus of elasti city The ratio of lengths of two wires made up of the same material is 3 :1 and the ratio of their radii is 1:3. The ratio of increments of lengths on account of suspending the same weight will be ...211. The following four wires are made of same material. Which one will have the largest elongation whersubjected to the same tension ? (1) Length 500 cm, diameter 0.05 mm. (2) Length 200 cm, diameter 0.02 mm. (3) Length 300 cm, diameter 0.03 mm. th of the (4) Length 400 cm, diameter 0.01 mm. A mass of 2 kg is suspended from a steel wire of length 1 meter to form a pendulum arrangement. If the mass is moved to one side and released from the horizontal position of wire then find the maximum extension denstiy of in the length of the wire. Fixed end s modulus The bulk's modulus of copper is 138 x 10° Pa. The additional pressure generated in an explosion chamber is 345 x 106 Pa. Then the percentage change in the volume of a piece of copper placed in this chamber will be 0.25 % (Given-Y = 2-x101 N/m2 and area of cross-section of wire = 1 mm, g = 10 m/s) sted is 4 x 105. Decrease in the volume of 100 cxn...(3 and 4)
