I'm a programmer who's been put in charge of some motor control problems and I need your help, so please forgive me if the question is silly.
The problem in question (see inserted picture) is basically whether or not I should factor in the entire mass of the (bifold with horizontal hinge) door into the lifting load of the hoist, or if some of that load will be absorbed by the building (we can disregard any forces absorbed by the building structure here):
So if the total weight of both halves of the door is 200 pounds, should I treat the holding torque of the hoist as 200 pounds * Gravity?
If not, how is the total force on the pulley line calculated from the 200 pounds of total door weight?
Thanks in advance for your assistance!
