For the pipe shown in Figure $1,$ a distributed load acts on the vertical part of the pipe, along

with a vertical force $P=8000N.$ Details of the distributed load are also shown in Figure $1.$

Note that the distributed load has a change in profile halfway through the beam, and the

pipe is fixed at point $O.$

a$)$ Determine the point load generated from the distributed load, and the location of

the point load.

b$)$ Determine the reaction forces observed at point $O.$

c$)$ Calculate the moment generated about the segment $OA.$
