S.E. Civil 2019 Pattern- Mechanics of Structures Practical's

3. Tile Abrasion Test

    The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive power revolving at the rate of 30±1 revolutions per minute. The wear of the tile is measured using a thickness gauge. The abrasion testing machine consists of a replaceable grinding path fitted on a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counter balanced lever. A funnel is provided to facilitate charging the grinding path with a brass save power. Supplied complete with automatic pre-set revolution counter and one 7.5 kg. weight but without abrasive power and thickness gauge. Please go through video for more details

 S.E. Civil 2019 Pattern- Mechanics of Structures Practical's 6. Torsion test on Mild steel using digital torsion Testing machine.      In torsion testing the circular bar is placed in the machine such a way that its longitudinal axis coincides with the axis of the grips and so that it remains straight during the test. Then rotate one grip at a reasonable constant speed until the test piece breaks, here the shearing stresses will develop in any cross section of the bar whose value increases linearly from zero at the center to a maximum at the outer periphery.
