The beam is subjected to the distributed loading. Determine the length b of the uniform load and its position a on the beam such that the resultant force and couple moment acting on the beam are zero.
Given:
{ w }_{ 1 } = 40 \frac { Ib }{ ft } \quad c = 10 ft
{ w }_{ 2 } = 60 \frac { Ib }{ ft } \quad d = 6 ft
