Solve the problem.

The strength S of a wooden beam with rectangular cross section is given by the formula
S = kd3 sin2 θ cos θ
where d is the diagonal length, θ the angle illustrated, and k is a constant that varies with the type of wood used.



Let d = 1 and express the strength S in terms of the constant k for θ = 45°, 50°, 55°, and 65°. Does the strength always increase as θ gets larger?
