A student did an experiment to determine the Youngs modulus (Y) of a nylon thread, 2.00 m in length, using Searles method. A Vernier callipers having a least count of 0.01 mm was used to measure the diameter of the thread. The length and extensions were measured by using a scale with a least count of 1 mm. The data obtained by the student are shown in the table below. Assume the uncertainty in force to be 0.01 N.
Length of the thread | 1994 mm |
Force | 0.32 N |
Extension of the thread | 95 mm |
Diameter of the thread | 0.04 mm |
