1. The problem statement, all variables and given/known data A 7kg cat walks to the end of a 15 kg board resting on two saw horses as shown below. When the cat is at the 1m position as shown, the board “just” lifts off of the left hand support. How long is the board? 2. Relevant equations T = D x F 3. The attempt at a solution I know that the torque on both sides has to be equal, but I have no idea how to approach this without knowing the length!
