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.
