I think the answer should be E because 0.75 fy.

Gajan Rana said:   9 years ago
According to me, the Correct answer is 0.66 fy.

Mahendra said:   9 years ago
Agree @Gajan.

It is 0.66fy.

For direct permissible stress 0.6fy.
Bending for rolled steel I-beams and channels 0.66fy.
0.66 * 250 = 1650 kg/cm2.

And for shear 0.4 * fy.

Thanks @Jaswant.

Karam said:   8 years ago
.66 fy, for minimum fy =250, .66*250=1650.

Viru kapoor said:   7 years ago
Agree with 0.66fy.

Abhik said:   6 years ago
The unit is in N/mm2 for fy

Suman said:   6 years ago
