A 30 m steel tape exactly at a temperature of 20° C and pull of 10 kg were used in a practical class to measure a line. The measured length was 1650 m. The temperature during the practical class was done is 30° C with a pull of 16 kg. Find the true length of the line, if the cross-sectional area of the tape given was 0.035 mm . The coefficient liner of expansion given for the tape per ° C is 3.4 x 10 and young modulus of elasticity is 2.0 x 10° kg/mm2 Q2.
QUESTION 21: A 50m tape of standard length has weight of 0.05kg/m, with a cross sectional area of 0.04sqcm. It has a modulus of elasticity, E = 2x106 kg/cm² The tape is of standard length under a pull of 5.5kg when supported throughout its length and a temperature of 20°C. This tape was used to measure a distance between A and B and was recorded to be 458.65m long. At the time of measurement, the pull applied was 8kg with the tape supported only at its endpoints and the temperature observed was 18°C. Assuming coefficient of expansion of steel tape as 0.0000116/°C. a) Compute the correction due to the applied pull. b) Compute the correction due to sag of the tape. c) Compute the true length of the measured line AB due to the combined effects of applied pull, sag and temperature.

A rigid bar is supported by two copper ro ds and the gap (A) between the aluminu m rod and the bar is 1.50 mm. If the temp erature for all materials is increased by 4 0 degrees Celsius, will the aluminum rod touch the rigid bar or not? Prove your ans wer by stating computed data. Disregard the weight of the rigid bar. For each copper bar, A = 500 mm^2, E = 120 GPa, and a = 1 6.8 μm/(m. C). For the aluminum bar, A = 400 mm^2, E = 70 GPa, and a = 23. 1 μm/(m.
