Imagine that you again push on a door, but
now push 1 and push 2 are applied at the same
place, near the door knob. Again, both pushes are
equally hard and equally long. The only difference
is that push 1 is perpendicular to the door, while
push 2 is at an angle, as drawn here. Although the
exact angle doesn’t matter, make it reasonably
small, under 45°.
Which push will produce a bigger torque? Intuitively, why is that?

You can try this at home! Or you can think about it...how do you push open a door? Do you push the door into it's own hinge, does that open the door? or do you push it perpendicular to the door itself?

It doesn't really make sense to open a door by push it into the hinge right?

so does push 1 produce a bigger torque?
