Beam AB is subjected to a triangular load as shown below. Determine the Resultant and its distance from A.

A simply supported beam has a symmetrical rectangular cross-section. If the second moment of area (I) of a beam with a rectangular cross-section is 11.50 x 106 mm4 about its centroidal x-axis and the depth dimension (d) of the rectangular section is 180 mm, determine the breadth dimension (b) for this beam section. Give your answer in millimetres (mm) and to 2 decimal places. Assume the beam section material is homogeneous.

Determine the (Couple Moment) in the beam) and its direction if [ F= W ]

The first moment of the shaded area with respect to the x axis is denoted by Qx (a) ) Express Qx in terms of b, c, and the distance y from the base of the shaded area to the x axis. (b) For what value of y is Qx maximum, and what is that maximum value?
