A line was measured with a (30m) tape. This is standardized at (20 °C) under a pull of (10kg). The measured length of line was (1500m). The temperature during measurement was (30° C) and the pull was (15kg). Find: - 1.) The corrected length of tape 2) The true length of the line Given the following: Coefficient of expansion= 3.5 x 10 per °C Modulus of Elasticity = 2.1 x 10° kg / cm² Cross - sectional area of the tape- 0.020 cm?

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.
