PROBLEM 7.88
For the beam and loading shown, (a) write the equations of the shear
and bending-moment curves, (b) determine the magnitude and
location of the maximum bending moment.
PROBLEM 7.89
The beam AB is subjected to the uniformly distributed load shown and to
two unknown forces P and Q. Knowing that it has been experimentally
determined that the bending moment is
800 N m+⋅
at D and
1300 N m+⋅
at E, (a) determine P and Q, (b) draw the shear and bending-moment
diagrams for the beam.
