Answer:

Explanation:
Given that
Shear modulus= G
Sectional area = A
Torsional load,

For the maximum value of internal torque

Therefore

Thus the maximum internal torque will be at x= 0.25 L
![t(x)_{max} = \int_{0}^{0.25L}p sin( \frac{2\pi}{ L} x)dx\\t(x)_{max} =\left [p\times \dfrac{-cos( \frac{2\pi}{ L} x)}{\frac{2\pi}{ L}} \right ]_0^{0.25L}\\t(x)_{max} =\dfrac{p\times L}{2\times \pi}](https://tex.z-dn.net/?f=t%28x%29_%7Bmax%7D%20%3D%20%5Cint_%7B0%7D%5E%7B0.25L%7Dp%20sin%28%20%5Cfrac%7B2%5Cpi%7D%7B%20L%7D%20x%29dx%5C%5Ct%28x%29_%7Bmax%7D%20%3D%5Cleft%20%5Bp%5Ctimes%20%5Cdfrac%7B-cos%28%20%5Cfrac%7B2%5Cpi%7D%7B%20L%7D%20x%29%7D%7B%5Cfrac%7B2%5Cpi%7D%7B%20L%7D%7D%20%20%5Cright%20%5D_0%5E%7B0.25L%7D%5C%5Ct%28x%29_%7Bmax%7D%20%3D%5Cdfrac%7Bp%5Ctimes%20L%7D%7B2%5Ctimes%20%5Cpi%7D)
