Final answer:
To find the maximum shearing strain, calculate it using the formula γ = F / (A * G) where G = E / (2 * (1 + v)).
Step-by-step explanation:
The equation gives the shear strain (γ):
γ = F / (A * G)
where F is the shearing force, A is the area of the object, and G is the material's shear modulus.
In this case, the Poisson's ratio (v) is 0.3. The shear modulus (G) can be related to the Young's modulus (E) and Poisson's ratio (v) by the equation:
G = E / (2 * (1 + v))
Substituting this value of G into the shear strain equation and solving for γ will give the maximum shearing strain.
