Sorry for the late reply.
T = 40/ cos(alpha) + 0.4sin(alpha)

Is that 40cos⁡α+0.4sin⁡α\dfrac{40}{\cos \alpha} + 0.4\sin \alpha

or is it 40cos⁡α+0.4sin⁡α\dfrac{40}{\cos \alpha + 0.4\sin \alpha}

Then you need the maximum value of the denominator so you will want to use Rsin⁡(α+β)R\sin (\alpha + \beta)

I have done c3 but havent come across that formula rsin (alpha+beta).

How about Rsin⁡(x+α)R \sin (x+\alpha )

It appears it is in c4 (I just chcked my book). Ah well I guess I should probably learn that before going back to the question.
I never thought c4 would be in m2 we haven't even started c4 :frown:
