The figure shows a cantilever beam fixed at its right end which is labeled B. The x axis is taken along the length of the beam. The y axis is taken perpendicular to the beam at its left end. The length of the beam is 11 meters. The load at the left end of the beam has a magnitude of 6 kilo newtons and is directed vertically downwards. The load at a point on the beam which is 4 meters from the left end has a magnitude of 11 kilo newtons and is directed vertically downwards. The reaction force at the right end of the beam has a magnitude of 17 kilo newtons and is directed vertically upwards. The reaction moment at the right end of the beam is 143 kilo newton meter and is directed clockwise.
