A 100- m steel tape is used to measure the distance of the line and found to be 1539.28- m long. During measurement, the tape is supported at the ends under a pull of 10- kgs and the observed mean temperature is 31°C. The tape is of standard length at 20 °C and a tension of 12- kgs. The cross sectional area of the tape is 0.035 cm2. The coefficient of linear expansion is 0.0000116/°C and the modulus of elasticity of steel is 2.0 (10)^6 kg/ cm2. The tape weight is equal to 1.5- kg.  a) Determine the total correction for temperature. b) Determine the total correction due to tension. c) Determine the total correction due to sag. d) What is the correct length of a line?

Dependence on mechanical properties

The mechanical properties of materials are those structures that include the reaction to the load used. Metal switching features determine the scope of the usefulness of the content and establish the expected service life. Machine structures are also used to help distinguish and identify material objects. The most common mechanical properties considered are strength, ductility, stiffness, impact resistance, and resilience to fractures.
