Please show work for a god review and so I may compare with my answers.
To get full credit you must draw a free-body diagram any time you use equilibrium equations to calculate forces or moments. Discuss the solution to this exam with your instructor. Determine the coordinates (ye, ze) of the centroid of the cross section in figure P1.6, the area moment of inertia about an axis passing through the centroid of the cross section and parallel to the z-axis. A distributed load acts on a symmetric C section, as shown in figure P1.7. Determine the force F and its location that is statically equivalent to the distributed load. Find the internal axial force send the internal torque acting on an imaginary cut through point E in figure P1.8. A simply supported beam is loaded by the uniformly distributed force of intensity 0.1kip/in. applied at 60 degree, shown in figure P1.9. Also applied is a force F at the centroid of the beam. Neglecting the effect of beam thickness, determine at section C, the internal axial force, the internal shear force, and the internal bending moment. A system of pipes is subjected to a force P, as shown in figure P1.10, by inspection indentify the zero and non-zero internal forces and moments. A indicate the table the coordinate directions in which the internal shear forces and internal bending moments act.Explanation / Answer
1. yc = (A1y1 - A2y2) / (A1-A2)
= ( 12*8*4 - 6*8*(2+3) ) / (12*8 - 6*8)
= 3 in
zc = 0 from symmetricity
so C = ( 3,0)
