Question

Equal masses are suspended from two separate wires. The wires have identical lengths. The first wire has a larger cross-sectional area than the second wire. Which wire will stretch the LEAST? Equal masses are suspended from two separate wires. The wires have identical lengths. The first wire has a larger cross-sectional area than the second wire. Which wire will stretch the LEAST? A. The first wire will stretch the least. B. The second wire will stretch the least. C. Both wires will stretch the same amount. D. The answer cannot be determined from the information given.

Explanation / Answer

"Spring Constant, K" of a wire = Area * Youngs Modulus / Length... Here length and type of wire is same...so K will be directly proportional to Area of C/S Also, Larger the value of K...Smaller will be the deformation... Hence...A. 1st Wire will stretch least
