Determine The minimum cross sectional area of link AB to prevent failure if it is made of 1020 hot-rolled steel (Sy = 290 MPa, Su = 475 MPa).

(c). The minimum cross sectional area of link AB to prevent failure if it is made of 1020 hot-rolled steel (S, = 290 MPa, S,-475 MPa). 2000 N 3000 N 45° 45° 1000 mm 45° 45°

Solution

FOS=S_y/S_u=1.6=2

S_u=P/A

A=Pi*D²/4

D=28mm

So C/S Section Area to prevent failuer = 30mm Dia.
