A fulcrum is placed 1.20 m from the edge of a 3.70 m-long wooden uniform plank that weighs 190 N. A weight F, is placed at the edge of the short end to balance it. How large must this weight F, be in order to balance the plank? (Hint: first draw the weight vectors each in the correct location) 3. 1,20 m 3.70 m ----
