Question

t=10 mm b=240 mm F.S=1.9 σall=230 MPa

1. The vertical force P acts on the bottom of the rod having a negligible weight and a
rectangular cross section. The rod has a thickness of t(mm) and Pacts along the center
line of this thickness.
a) Determine the shortest distance d to the edge of the rod at which it can be
(eccentrically) applied so that it produces no compressive stresses on the rod at
section a-a (Case in Figure A).
b) What would be the maximum value of P for the given allowable stress Oall and
Factor of safety F.S if P was applied at the middle of the rod (Figure B)?
