When the person holds a hay over his head for 30 mins, even if he gets tired, but according to physics, there is no work done as in this case, the person doesn't displace from one point to other. The mathematical explanation is as follows :-
Work done = Force x Displacement
Here, displacement is zero, so -
Work done = Force x 0
∴ Work done = 0 Joule
