【Abstract】 The measurement of Young’s modulus of elasticity is one of the basic experiments conducted in the laboratory session in college physics. In analyzing the measuring error caused by inaccurate adjusting of light lever reflector or vertical ruler, it attempts to call attention to experimental method and idea with respect to the satisfaction of experimental conditions and the effect on the experimental result.更多还原
