Let t be tension in rope. Then upward force on the clamp is tsin30°≈t/2≈360N.

T≈720N

Let a be acceleration of man in upward direction then,

T-600N≈60 kg . a

Therefore maximun acceleration of the man is

a≈ (720-600)N/60 kg. ≈ 2m/s^2.

Now my question is if we draw the tree body diagram of the wooden clamp we should include the normal contact force by the rope and the ground.Therefore upward force on the clamp is the resultant of the of the normal contact force by the rope and the tension in it. Why then we only consider the tension in the rope as the only upward force.
