[Note: Thread moved from General Physics, so no template is shown] Sorry guys, beginner here taking an online introduction physics course. I'm on a unit involving torque and force. The computer lab taught me how to calculate the force needed to balance a seesaw type setup on the left side, with a given weight on the right side. Easy enough. But one of the questions my instructor has given me seems a bit different, or maybe I'm not getting the point.. "Use the sum of vertical forces and torque equations to calculate the force at the Left and Right end of a 10 foot long plank that has a 200 lb weight 3 ft from the left end.." Shouldn't there be some type of axis that the plank sits on? Any help would be much appreciated Thanks guys!
