Problem 10. The A-36 steel plate has a thickness of 12
mm. If there are shoulder fillets at B and C, and
O allow
= 150 MPa, determine the maximum axial load P
that it can support. The maximum stress at the fillets
can be determined from the formula Omax = K Gave,
where K is the stress concentration factor for fillets
given in Graphs in Section 4.7 of Hibbeler textbook, and
based on the fillet radius to small width and large width
to small width ratios. Also compute its elongation
neglecting the effects of the fillets.
