The angle is θ = 55.0°. The masses are, for the small pulley, m1 = 3.1 kg, for the traveling pulley, M2 = 5.7 kg, and for the crate, MC = 41.0 kg. What is the minimum tension with which the operator must pull on the cable (assume the cable is of negligible mass) in order to slowly raise the crate.

My book shows an example of the equation:
2 x F(T) - mg = ma
I'm not sure if that's the equation to use and if it is, how do I apply it?
