I understand the concept of moment of inertia but can't comprehend the first equaion here. The other two i get and they are moments of inertia of other two bodies. (the left and right)

Now what's left out from the pictures is that the tensions are:
##T_1=mg-maR## and ##T_2=mg+maR##
and so its continued like this:
The moment is ##M=F*R## but i fail to see what the first term represents and what's with the signs?
The last part is:
