You hang a mass (weight of masses can be anything) from the middle of plastic while plastic straw is connected to two pivots with the same height. Measure the elasticity and try this with three different masses and complete the table and answer the following questions Trial Mass 1 Mass 2 Mass 3 Mean Mass of hanging object (kg) N/A Standard N/A deviation Width of the beam w(m) N/A N/A Height of the beam h(m) N/A N/A Length of the beam L(m) before deflection N/A N/A Deflection from the string that connects object 2 to the balancing rod to the pivot point at the center of the beam d(m) N/A Note: you can also find this using Pythagorean theorem for column sixth The significant figures for the values of the measurements you get and enter in the tables should match the uncertainty in your measurement devices. For example if your ruler can only measure up to a millimeter, any SI measurements should have three significant figures, e.g., 0.250m. If you do not know how to increase/decrease the significant figures in a cell in Excel, a quick internet search will help. Computed young's modulus Y(Pa)
