Answer:
Shear Modulus = 2500 Pa = 2.5 KPa
Step-by-step explanation:
The shear modulus is defined as the ratio between the shear stress and the shear strain. Hence, the shear modulus, in this case, can be calculated by the use of the following formula:
we have,
shear stress = 20 N/m²
shear strain = 0.008
Therefore,
Shear Modulus = 2500 Pa = 2.5 KPa
