Question: a steel beam ixx1690 in4 section height 18 inches...

Question details

A steel beam (Ixx=1690 in4, Section Height = 18 inches, E = 29,000 ksi, fy =60ksi) is supported at A and B as shown below. What is the magnitude of the uniformly distributed load if a strain gage at the top of the beam at B measures 0.00207 in/in strain?

STRAIN GAGE Lie tr 18

a. Find the reactions in terms of the unknown distributed load (w).
b. Draw the shear and bending moment diagrams in terms of the unknown distributed load (w). Label the distance from the start of the beam where the shear or bending moment are zero, or have a local maxima or minima, label the values of local maxima and minima.
c. Determine the magnitude of the moment at B given the strain gage measures 0.00207 in/in strain.
d. Determine the magnitude of the distributed load (w).
