Use any simple rigid structure such as a lamp post or a bridge

Only 1 and 2, Thanks!

Module 1b. Equilibrium of a Rigid Body 1.1 OBJECTIVE To appreciate the application of equilibrium of a rigid body (structure) in our daily life. 1.2 ACHIEVEMENT OF UNIT LEARNING OUTCOMES (ULO) The unit learning outcomes that have been achieved by this assignment are summarized in Table P1. 1 Table P1 Learning outcomes that are achievable by take-home assignment 1 Achievable ULO ULO Description By This Assignment Discern and determine the magnitude of loads acting on simple structural members 2. Analyse rigid body equilibrium including: a. Construct free body diagrams showing the function of simple structural elements b. Analyse the force (s) or moment required to maintain a structure in equilibrium C. Analyse external reactions on structural members under applied loading d. Construct axial force, shear force and bending moment diagrams for simple beams. 3 Analyse the behaviour of structural members including: a. Analyse section properties for simple cross sections b. Analyse internal axial stresses, shear stresses and bending stresses in structural members such as beams, trusses, ties, struts, shafts and bolts.
