An escalator is driven by a chain connected to point A that supports a force F . The rollers at points A and B have frictionless bearings and ride in a loose-fitting track. If a person weighing 200 lb is being lifted at a steady speed and other weights may be neglected, determine the required chain force F and the reactions at the wheels at A and B. If the person is being lifted at a variable speed, will the force F be different than that calculated earlier? Explain.
