Lab 1: Measurement and Propagation of Errors Objective: To learn the fundamentals of measurement and propagation of error. Procedure: Wear gloves. Measure the mass of the cylinder with a triple beam balance scale and determine the volume of the cylinder by measuring the diameter d and the height h with a caliper. The volume of the cylinder is then V = (pi)(d^2)h/4. The density p = m/V = 4m/(pi)(d^2)h. Observe an record data. Repeat for two other cylinders. Measure the volume of the cylinder via water displacement in a graduated cylinder, observe and record data, and calculate density. Repeat for two other cylinders. Data: (See attached) Calculations: (See attached) Conclusion and Error Analysis: Based on the calculated densities, the physical properties of the cylinders, and the potential metals available to us, the cylinders can be identified as follows: 1 – lead (19.75%); 2 – copper (9.72%); 3 – iron (12.20%). There is a possibility that cylinder 3 was Zn or Cr, but the physical
