A steel wire of length L with a cross-sectionaldiameter d is wrappedover a light frictionless pulley, wiht one end of the wireconnected ot a mass m1 and the other endconnected to mass m2 .
a.) How much will the wire stretch while the massesare moving?
b.) Determine the numerical value of htis stretch if L=2.0 m,d= 4.0 mm, m1 = 5.0kg,and m2=3.0kg.
