Question

No 1 pliss dijawab . tak kasi poin banyak

Answer 1

A. e = delta x / x = 0.004/0.5 = 0.008 m
b. tegangan = F/A = 12/0.003 = 4000
c. E = tegangan/regangan= 4000/0.008= 500.000

semua satuan panjang diubah ke dalam meter.

Answer 2

Dik : x1 = 50 cm = 0.5 m.
x2 = 50,4 cm = 0.504
F= 12N
A= 3 cm= 0.03m
dit: b. tegangan a. regangan. c. modulus elastifitas
a. regangan = x2/x1 = 0.504 / 0.5 = 1.008;
b. tegangan = F/A = 12/ 0, 03 = 400
c. modulus elastifitas = tegangan / regangan = 400/ 1.008 = 396.82
