A tent peg made from a circular steel rod is embedded in the ground as shown in the figure below. The peg has an overall length of 150 mm and is embedded into the ground a distance, L, of 117 mm. The diameter, d, of the peg is 5 mm. To remove the peg from the ground, it is necessary to generate an average shear stress between the peg and the ground of 24 kPa, which is generated by applying a vertical force, P, as shown in the figure. At the point at which P is just sufficient to remove the peg from the ground, calculate the maximum tensile stress, max, generated within the peg at plane A-A. Give you answer in MPa to two decimal places

Question
A tent peg made from a circular steel rod is embedded in the ground as shown in the
figure below. The peg has an overall length of 150 mm and is embedded into the
ground a distance, L, of 117 mm. The diameter, d, of the peg is 5 mm. To remove the
peg from the ground, it is necessary to generate an average shear stress between the
peg and the ground of 24 kPa, which is generated by applying a vertical force, P, as
shown in the figure. At the point at which P is just sufficient to remove the peg from
the ground, calculate the maximum tensile stress, max, generated within the peg at
plane A-A.
