Question

(4) Problem 4: Stress and Strain (8 Points). The rigid bar "AD" is subjected to a point load at "D". There is no strain in rods "BE" and "CF if"p=0". After "P" is applied, the normal strain in rod "CF" is "0.0007 mm/mm Determine: (a) Axial Normal Strain EBE. prion command (b) Axial Normal Strain EBE if there is a "5 x 10" m" gap in the connection between the rigid bar and rod "CF" before the load "P" is applied.
