How much work are you doing if you push on a 40 N rock that won't move?

Work is defined as the product of (force) x (distance).
If you push on something that won't move, then although you may break out
in sweat, and possibly even become short of breath, the distance is zero, so
by the strict definition of 'work' in Classical Mechanics, the quantity of work done
is zero.

If the rock does not move then no work is being done.
======================================
Work is not defined as "accomplishing something".
It's defined as a force moving through a distance.

You exert a force of 75 newtons on a rock. You push and you push, but you can’t budge it. You are exhausted! How much work did you perform?
Unfortunately, 0. The rock has 0 displacement, so despite force being exerted no work was done (at least in physics terms).

How do you use a lever?
It is used to lift a heavy object. Place the end of the lever under the rock. Then move a fulcrum (for example a small rock) under the lever close to where it goes under the rock. By moving your end of the lever a lot, you can make the shorter end move a little and lift a heavy weight.
