Caption states: "Experimental error curves with solid masses. Steep slope of curve is caused by excessive zero mass of pendulum which will be designed out in future. Accuracies on this order may be obtained at greater or less mass by changing spring constants."Space medicine.Space flight--Physiological effect.Weightlessness--Physiological effect.Skylab Program.Image
