Unformatted text preview: EAS 207  STATICS Final Exam
Fall 2002 Total points: 100 Notes: (i). Closed book exam.
(ii). Do all problems.
(iii). Draw Free~body Diagrams and reference axes. Problem #1: Find the pin forces at G and supportmg forces at A and B of
the loaded frame shown in Fig. 1. (20 Points) Problem #2: Blocks A and B, shown in Fig.2, weigh 50 lbs and 30 lbs,
respectively. Determine the greatest weight of block D without causing motion. (20points) » Problem #3 a) Determine the Moments of inertia Ix, ly, lxy for the composite section shown in Fig. 3 (13 points)
b) Determine the principal moments of area at point A. (7 points) Problem #4
a) A beam is loaded and supported as shown in Fig. 4.
i) Calculate the support reactions. ( 5 points)
ii) Write the shear force and bending moment equations for a beam
section between points D and E. ( 7 points) b) Draw complete Shear and bending moment diagrams for the beam with
the aid of the area integration process. Be sure to label the values of
shear force and bending moment on the diagram. (13 points) Problem #5: A freshwater channel 10 ft wide (normal to the plane of the  paper) is blocked at its end by a rectangular barrier, shown in section ABD
(Fig. 5). Supporting struts BC are spaced every 2 it along the 10 ft width.
Determine the compression in each strut. Neglect the weight of the ,
members. ‘ ' _ (15 points) 60° 60 (,9) Hit/L39 (or (Pin) Ohm/“13hr” {\onsl Exam .
