A prismatic beam is built into a structure. You can consider the boundary conditions at A and B to be
fixed supports. The beam was originally designed to withstand a triangular distributed load, however,
the loading condition has been revised and can be approximated by a cosine function as shown in the
figure below. You have been tasked with analysing the structure. As the beam is prismatic, you can
assume that the bending rigidity (El) is constant.

In order to do this, you will:
a. Solve the reaction forces and moments at point A and B.
Hint: you may find it convenient to use the principal of superposition.

b. Plot the shear force and bending moment diagrams and identify the maximum shear force
and bending moment.

Question 1: Beam Analysis
Two beams (ABC and CD) are connected using a pin immediately to the left of Point C. The pin acts
as a moment release, i.e. no moments are transferred through this pinned connection. Shear forces
can be transferred through the pinned connection. Beam ABC has a pinned support at point A and a
roller support at Point C. Beam CD has a roller support at Point D. A concentrated load, P, is applied
to the mid span of beam CD, and acts at an angle as shown below. Two concentrated moments, MB
and Mc act in the directions shown at Point B and Point C respectively. The magnitude of these
moments is PL.

FBD's you must make section cuts at point B and C. You can represent the structure as three
separate beams. Following this, construct the…

Photograph of the new product (left). Picture sourced from amazon.com.au. To assess the design, you will: a) Determine state of stress at all points (a, b and c). These points are located on the exterior surface of the beam. Point a is located along the centreline of the beam, point b is 15mm from the centreline and point c is located on the edge of the beam. When calculating the stresses you must consider the stresses due to bending and transverse shear.
