Determine the sheer stress (in ksi) of pin C if structure shown is being designed to support a 6.4 kip load. Pin C has a diameter of 0.7 in, LAB IS 15.2 in and LBC is 6.4 in

Answer 1

Giren data: P = 6.4 kip LAB = 15.2 in LBC 6.4 in. d=07 in . Now, FBD of beam ABC becomes. FRA Hc VRO B P IS2 in 6.4 in. n take moment at B, ie. EMB=0. 64X 15.2 - Rcx64=0 Rc=15-2 kip Hc=o. take Efx=0 At p connection i, pian is subjected to duble Shear and corresponding shear stress becomes Rc T n=2 for double [Here, nx Id² Shear 15.2 2 x 7 x 0.72 IT = 19.76 ksi
