With reference to the bolts in Problem 2.67,
(a) If they are brittle and each one fractures at a load of 6000 N, what maximum force F can be applied to the bracket?
(b) What load can be applied if they are ductile, and each bolt has a yield strength of 6000 N?
Problem 2.67
A "T" bracket, attached to a fixed surface by four bolts, is loaded at point E as shown in Figure P2.67.
(a) Copy the drawing and sketch paths of force flow going to each bolt.
(b) If the stiffness between point E and the plate through bolts B and C is twice the stiffness between point E and the plate through bolts A and D, how is the load divided between the four bolts?
