Question details



QJ. IMechanical Attributes &Design/ A bridge is in the process ofbeingconstructed that must bare large loads Assuming (for the sake of simplicity) that the structure is suspended by means of two steel alloy cables that equally share an overall load f 2,000,000 N. The stecl alloy of choice possesses a modulus of resilience in the vicinity of 2.07 MPa Due to the dire consequences normally associated with the failure of such a structure, past experience dictates that a factor of safety of up to 4 is adopted a The engineering value for the yield strength corresponding to U, eshibited by the steel alloy would amount to 1043.65 MPa i. 8S6.12 MPa li. 621.36 MPa iv.925. 73 MPa b. The true value for yield strength vicinity amounts to: i 1053.65 MPa L 66.12 MPa 929.87 MPa lv. 635.23 MPa c. The safe stress based on the factors of safety advised would be i 32J.74MPa 232.47 MPa L 40S.77 MPa
iv. 504.77 MPa IV. d. The minimum diameter to be designed for each cable based on part (c) would be: i. 0.016 m ii. 0.025m In1 i 0.0SS m I1 iv.0.074 m IV.
