Q.1. Measurement of four lengths is given in Table.
Measured Length ( m ) | Temperature ( C ) | Tension ( N ) | |
1 | 29.899 | 18.0 | 178 |
2 | 29.901 | 18.0 | 178 |
3 | 29.882 | 18.1 | 178 |
4 | 29.950 | 17.9 | 178 |
The tape has a mass of 0.026 kg/m and a cross-sectional area of 3.24 mm2 . It was standardized on the flat at 20°C under a pull of 89 N. The coefficient of linear expansion for the material of the tape is 0.000011 per °C, and Modulus of elasticity of the tape is 20.7*1010 N/m2 . Determine the absolute total length.
Can anyone help me please ?
