Question
a) In Figure 5, cantilver beam AB supports a uniformly distributed load of 2kN/m and twi concentrated load P and Q. It has been experimentally determined that the normal stress due to bending on the bottom edge of the beam is -56.9MPa at A and -29.9MPa at C.
i) Determine the magnitudes of load P and Q.
ii) Draw the shear and bending-moment diagrams for the beam.
iii) Calculate the changes for load P and Q if the uniformly distributed load was increased to 4kN/m?
