I am in the process of building an antenna mast that can tilt from horizontal (down) to vertical (up). The mast (arm) is 360" and weighs a total of 105 lbs. I need to calculate the amount of force placed on a winch in order to lift the mast (arm) from the down to up position. All the formulas I am finding are for calculating the force required to lift a weight at the end of a leaver. It seems to me that this will not work in my case since the weight is distributed evenly over the entire length of the arm.
I have two options (plans) on how to place my winch. I need to determine which option will require the least effort but also the most stable.
Can anyone shed some light on this? I have attached a diagram.
