Cable stress formula
WebThe equation for change in length is traditionally rearranged and written in the following form: F A = Y Δ L L 0. 5.34. The ratio of force to area, F A, is defined as stress (measured in N/m 2 ), and the ratio of the change in length to length, Δ L L 0, is defined as strain (a unitless quantity). WebI determined that the tension would be different on each end, that the shape of the suspended cable would be a catenary curve truncated at one end, and that the following would be the variables necessary in the …

The thermal withstand of a cable can be determined by comparing the maximum energy at the fault, with the maximum energy the cable can absorb. The equation for this is: I 2 t ≤ k 2 A 2. I2t is proportional to the energy let-through of the protective device. I - fault current, A.
WebFeb 13, 2024 · We calculate the strain is the rod according to the formula:. We calculate the stress, using the stress formula: σ = F/A = 30×10³ / (1×10⁻⁴) = 300×10⁶ = 300 MPa. Finally, we divide the stress by strain to … WebFeb 20, 2024 · Suspension cables are used to carry gondolas at ski resorts. (See Figure) Consider a suspension cable that includes an unsupported span of 3020 m. Calculate the amount of stretch in the steel cable.
