calculate the diameter of a silver wire of length 75cm , which is extended by 1.85mm when a 10kg mass is suspended from it's end . Young modulus for silver is 7.9×10^10N/m²
1 answer:
Answer:
Explanation:
Given
length of wire
change in length
mass of wire
Young's modulus for silver
load on wire
change in length is given by
Where A=area of cross-section
also wire is the shape of cylinder so cross-section is given by
