College Physics 1 (Algebra-based)

Calculate the force required of the "deltoid" muscle, Fm, to hold up the outstretched arm shown in the figure below. The total mass of the arm is 3.31kg. Assume that alpha = 15.2°, d = 12.0 cm and D = 24.0 cm.

Any help (at least how to set up the problem) would be great, thanks!
