Problem 2 (20 points)-A vertical column of 1018 hot-rolled steel ( kpsi, kpsi, kpsi, kpsi) is 10 in wide. An attachment of the same material has been designed to support

a static load of 20kip at a clearance in as shown in the figure. The attachment is welded with a E6010 electrode ( kpsi, kpsi, kpsi). The length of the weld bead is given by in and in. (a) Determine the primary shear on the weld as a function of theleg size . (b) Determine the secondary shear on the weld at a critical pointas a function of the leg size . (c) Determine the total shear at the critical pointthe leg size .as a function of (d) Using kpsi, determine the leg size .
