MEM23061A Test Mechanical Engineering Materials Lab. BEAM BENDING The bending of beams is one of the most important types of stress in engineering. Bending is more likely to be a critical stress than other types of stress - like tension‚ compression etc. In this laboratory‚ we will be determining the Modulus of Elasticity E (also called Young’s Modulus) of the various materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections.

Unit 7 - Reinforced concrete slabs. (Study time allocation – 15 hours) Introduction. The topic of reinforced concrete slabs is somewhat related to that of beams but also needs to be considered as a separate unit. Types of slab. 1. Single span solid slab. 2. Single span ribbed slab. 3. Two way “waffle” slab. 4. Flat slab – No column drops 5. Flat slab showing column drop. Analysis of

cracking‚ shrinking and creeping of concrete. Therefore‚ reinforcement is placed at areas in the concrete where tensile stresses develop. In this report the reinforcement methods will for the most part be discussed in terms reinforcement in beams. Stresses in a beam develop as illustrated in the following figure: Choosing the right methods of reinforcement for a specific concrete element will depend on the properties of the concrete mix and the materials of which the reinforcement is made. The properties
