Writing a natural philosophy - Lab Report ExampleFenner and other (1984) indicated that the modulus of rigidity is given by the ratio of breed to dress strain often represented mathematically as /. As widely cited, modulus of rigidity is essential in measuring the materials shear stiffness and it is known to be analogous to Youngs modulus for any elastic behaviour in compression or tension (Benham, Crawford & Armstrong, 1996). Given that a tensile material component useful in providing shear, an individual need to note that the maximum shear stress is safety, which is less than the materials yield shear stress (y). However, a brittle material the criterion of failure is establish upon its tensile stress (Gere &Timoshenko, 1984). Research indicate that the theory of complicatedness often give the torque in form of rotation asThe equation 1 above is often derived from Hookes law and it is withal valid for the shear stresses though somewhat lower than shearing proportional limit ( Case, Chilver & Ross, 1993). In a solid circular segmentation, it has been outlined mathematically that the polar second moment of the area of cross section is given by equation (2) (Ryder, 1969)In this experimental set up, there were various sets of apparatus used. Among them were the knottiness machine, a torsion bar, a gearbox, a torque meter, two protractors, a counter, and a reach-wheel. This way, a torsion machine was used for carrying out a test involving a specimen that was accommodated within the socket at all(prenominal) end. The 601 reduction gearbox served the purpose of manually applying the angular displacement at the left- hand side. The torsion bar was essential in this experiment given that it was used for measuring the torque when at right-side with a torque meter being used for reading digital data. The two protractors listed above were full of life in this experiment since they were used for purposes of measuring the rotation of the specimen. They were put at the gearbox, in which case, one was placed at the input hand wheel
