1. The problem statement, all variables and given/known data Imagine raising a long ladder by "walking" it from a horizontal position to a vertical one as illustrated n the Figure. The first few steps are not difficult, but the job becomes increasingly difficult. However, beyond a certain point the job becomes easier again and when the ladder is vertical all you have to do is keep the ladder balanced. Consider a uniform ladder of mass m and length l, lying on the ground with its base anchored against a brick. The ladder is slowly raised to a vertical position by applying a force at a constant height h above the ground. Consider the case where the ladder is raised using minimal effort. a)Find the angle the ladder makes with the ground when lifting force is a maximum. b)Find the magnitude Fmax of this maximum force. 2. Relevant equations torque = rF sin(theta) 3. The attempt at a solution I used L for r and Fmax was when it had the max force. So i tried using mg for the force of the ladder, but i'm unsure how to apply height in finding the Force, since using mg the force is the same no matter what. Some tips to help me in the right direction would be appreciated.
