A see-saw made from 4 meter board sits on a pivot at its center.A child weighing 280 N sits 1.75 m away from the center. A secondchild who weighs 330 N sits on the other side such that the boardremains horizontal and steady.
Now you come and push on the end of the seesaw nearest thesecond child with a force of 110 N. You donâ€™t push straight up, butat an angle of 25Â° from the vertical â€“ tilted a bit toward thecenter of the seesaw. The first child moves to maintainequilibrium.
