L = 80 cm, f = 100 n, delta L = 0,51 mm, diameter = 0,125 cm, r = 0,12265cm, A = 2 .phi .r .(r + t) = 2. 3,14.0,12265.(0.12265 + 80 ) = 61,74201.
a. tegangan = f/a = 100 / 61,74201 = 1,62 n/m persegi
b. regangan = delta l/l = o,51/800 = 0,0006375
c. modulus young = tegangan/ regangan = 1,62/0,0006375 = 2541,176 N/m persegi
