In these kind of figures how I can determine the motion where it is going right
or left ?
For example in figure Q6 :
Shall I write: mg sin e - 2 T= ma
Or mg sin e-2 T= - ma
I'm confused actually.

Similarlly for the cylinder
Shall I write :
3T- mg = ma
Or mg – 3T = ma or (-)
I don't know
Can you please exoain to me the directions
