Effect of Concentration of KCl, Temperature of Surroundings, and Length of Muscle on the Tensilie Strength of Muscle Tissue
The purpose of this experiment was to see how concentration of potassium chloride, temperature of surroundings, and length of muscle affect the tensile strength of muscle. To do this, we cut strips of perch muscle and placed them in different concentrations of potassium chloride at different temperatures. We then used a 10N Dual-range Force Sensor and LoggerPro to measure the amount of force, in Newtons, the muscle was able to withstand. These results were recorded and used to perform a 3-factor Design of Experiment (DOE). The results of our DOE showed that none of the factors – concentration of potassium chloride, temperature of surroundings, and length of muscle – had a significant affect on the tensile strength of muscle.
