**drwls**, Saturday, December 11, 2010 at 5:33pmT1 + T2 = (70 + 15)*g is one equation you need.

For the other equation, set the moment about either end equal to zero. If the painter stands 2 m from end 1,

T2*4.7 - M(board)*g*2.35 - M(painter)*g*2 = 0

Solve for T2. Then use the f1rst equation for T1.
