(Solved): A symmetrical framework consisting of three pin-connected bars is loaded by a force P (see figure). ...
A symmetrical framework consisting of three pin-connected bars is loaded by a force P (see figure). The angle between the inclined bars and the horizontal is
a=60\deg . The axial strain in the middle bar is measured as 0.0365 . The frame is constructed of a copper alloy having the following stress-strain relationship
\sigma =(18000\epsi )/(1+300\epsi ),0<=\epsi <=0.03,(\sigma in ksi)Determine: a. The axial strain of the outer bars in the loaded condition. b. The tensile stress in the outer bars. c. The yield strength of the copper alloy using the
0.2%offset method.
