1. The problem statement, all variables and given/known data If you are trying to loosen a stubborn screw from a piece of wood with a screwdriver and fail, should you find a screwdriver for which the handle is (a) longer or (b) fatter? 2. Relevant equations [itex]\tau[/itex] = r * F * sin([itex]\theta[/itex]) 3. The attempt at a solution I guessed longer because i figured that the larger radius would mean that you have a larger torque and need less force than if the radius was short, however the correct answer is B. Can someone explain this to me please?
