Question:-
A rod having cross-sectional area 100 x 10-6m2 is subjected to a tensile load. Based on the Tresca failure criterion, if the uniaxial yield stress of the material is 200 MPa, the failure load is
Option (A)
10 kN
Option (B)
20 kN
Option(C)
100 kN
Option(D)
200 kN
Correct Option:
(B)
Question Solution:
Tresca theory
tmax = (s1-s2)/2 = sy/2
Since s2 = 0
Therefore s1 = sy (s1 = force x area) force = 200 x 106 x 100 x 10-6 = 20kN
