Which one of the following is NOT a decision taken during the aggregate production planning stage?

A solid circular shaft needs to be designed to transmit a torque of $$50$$ $$N.m.$$ If the allowable shear stress of the material is $$140$$ $$MPa,$$ assuming a factor of safety of $$2,$$ the minimum allowable design diameter in $$mm$$ is

The homogeneous state of stress for a metal part undergoing plastic deformation is $$$T = \left( {\matrix{ {10} & 5 & 0 \cr 5 & {20} & 0 \cr 0 & 0 & { - 10} \cr } } \right)$$$

Where the stress component values are in $$MPa.$$ Using von Mises yield criterion, the value of estimated shear yield stress, in $$MPa$$ is

A fillet welded joint is subjected to transverse loading F as shown in the figure. Both legs of the fillets are of $$10$$ $$mm$$ size and the weld length is $$30$$ $$mm.$$ If the allowable shear stress of the weld is $$94$$ $$MPa,$$ considering the minimum throat area of the weld, the maximum allowable transverse load in $$kN$$ is
