^ This is the first case.
(friction) = f = μN = 0.05 (3 x 9.8) = ...? For equilibrium, (T - mgsin30 - f) = 0 ---(1) Mgsin60 - T = 0 ----(2) M = ....

yup i think on right tracxk
(friction) = f = μN = 0.05 (3 x 9.8) = ...? For equilibrium, ( mgsin30 - f -T) = 0 ---(1) Mgsin60 - T = 0 ----(2) M = ....
Then, you should get two answer... And compare them, identify which is m1, which is m2. Sorry, I'm not good at physics...
np thanks. that was actually a maths exam .. do you reckon its hard??
I learnt all that in physics lessons. Here, we include very little physics in maths. It's okay if you can draw the right free body diagrams.
