Answer:
Question:
A piece of rubber 10cm long stretches from 6mm when a load of 100N is hung from it. What is the strain?
Important Note (for solving your any problems):
In Physics to help for better understanding, it is important to write out
your given first.Given:
1. Original length = 10cm 2. Extension e= 6mm
3. The extension is meant to be in cm and to convert mm to cm, divide the number by 10.
Answer:
Strain = 0.6
Step-by-step explanation:
Solution:
Remember that,
[10 mm = 1 cm]
6 mm = (6 × 1) ÷ 10
-
= 0.6 cm
Load (force) = 100N
Recall that,
Strain = (extension) Original length
Strain = 0.6 cm ÷ 10 cm
Strain = 0.06
If you convert to standard form,
0.06 = 6 x 10^-2
- There is no unit because strain is a ratio of two lengths and they both have the same unit which cancels out during division.
