The two-bar structure shown is pinned at A, B, and C. A sign weighing 20 kN is suspended from bar BCat
points Dand E, which are located at 0.8 m and 0.4 m, respectively, from the ends of the bar BC. If member
AB is a steel pipe with inside diameter 20 mm, determine the smallest permissible outer diameter of the
member if the working stress in steel is not to exceed 140 MPa.

02.
Determine the smallest allowable cross-sectional areas of members JK, DK, and DE of the truss shown.
The working stresses are 120 MPa in tension and 80 MPa in compression. (A reduced stress in
compression is specified to reduce the danger of buckling.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F82d807ef-dd92-4fc5-bc40-f68cbee50ca1%2Fa95f4cca-0841-4253-804c-fb5c53754d58%2Ffasifbj_processed.jpeg&w=3840&q=75)
