What is the formula for calculating the theoretical shear strength ($\tau_{max}$) of a material?
What is the formula for calculating the theoretical shear strength ($\tau_{max}$) of a material?
- $\tau_{max} = Gb / a$
- $\tau_{max} = Gb / 2\pi a$ (correct)
- $\tau_{max} = 2\pi a / Gb$
- $\tau_{max} = a / Gb$
