Question

A wire of length 5.0m and diameter 2.0mm extends by 0.75mm,when a force of 50N was used to sketch it from its ends.Calculate (i)stress (ii) strain (iii) young modulus (π=3.142)

Answer 1

Answer:

. A force of 40N at the end of a wire of length 4m and diameter 2mm process and extension of 0.24mm. Calculate; (a) stress on the wire (b) strain in the wire (c) Young's Modulous for the material of the wire (π=3.14)
