An aluminum bracket with a 1 2-in thick flange is to be clamped to a steel column with a 3 4-in wall thickness. a cap screw passes through a hole in the bracket flange, and threads into a tapped hole through the column wall. specify a unc cap screw to provide a joint constant c of approximately 0.25.

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.
