All pins are in double shear, and each has a diameter of \( 21 \mathrm{~mm} . P=5 \mathrm{kN} \). (Figure 1\( ) \) Determine the average shear stress in the pin at \( A \). Express your answer to three significant figures and include appropriate units. \( \sim \operatorname{Part} \mathrm{B} \) Determine the average shear stress in the pin at \( B \). Express your answer to three significant figures and include appropriate units, Figure Part c Detemine the average sheor stress in the pin at \( C \). Express your answer to three significant figures and include appropriate units.
