To summarize, the shear modulus and torque-rotation graphs of brass, steel and aluminum have been calculated in this lab experiment. When compared to the published . The torsion test method is a mechanical testing technique used to evaluate shear modulus (G) of materials, including timber. . both torque and relative rotational displacements are measured at two specific sections, labeled as Section 1 and Section 2 in . Using the test results, plot a graph that represents the relationship between the . Introduction To put meaning to the data and conclusions drawn in this experiment several things must be known about the materials tested and the theory behind torsion testing. The two materials tested, cast iron and mild steel, have opposing characteristics. Steel is classified as a ductile material, a ductile material is known to be able to experience very large . The most common method for plotting a stress and strain curve is to subject a rod of the test piece to a tensile test. This is done using a Universal Testing Machine. It has two claws that hold the two extremes of the rod and pull it at a uniform rate. The force applied and the strain produced is recorded until a fracture occurs.

In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain.It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).These curves reveal many of the properties of a material, such as the Young's .In particular, the results from the torsion test will be compared to the results of the engineering tensile test for a particular alloy using the effective stress-effective strain concept. EQUIPMENT • Constant-diameter gage section torsion specimen of 6061-T6 aluminum • Torsion test machine with grips, troptometer, and force sensor. PROCEDUREA specially designed testing setup was used for the torsion test, as shown in figure (1) below. The system is comprised of a 2024-T4 aluminum shaft held on each end by one locked and one free support. Just inside the free support is a rigidly attached beam for application of a torque to the shaft, creating pure

PART A – TORSION TESTING OF CIRCULAR SHAFTS 1- Turn ON the Torsion Tester and install a steel shaft with a diameter D = 4.6 mm and a free length L = 300 mm. 2- With no weight mounted on the hanger, zero the angle of twist indicator. 3- Mount a 10-N weight on the hanger and record the angle of twist, to the nearest 0.1°, in the given table .2.3 Avoiding and Minimizing Torsion The commonly used structural shapes offer relatively poor resistance to torsion. Hence, it is best to avoid torsion by detailing the loads and reactions to act through the shear center of the member. However, in some instances, this may not always be possible. AISC (1994) offers several sugges- Introduction. Torsion test is carried out to determine the shear modulus of structural materials, such as steel and aluminum. Shear modulus is a material property that is useful in calculating the compliance of structural materials in torsion, provided that they follow Hooke’s law; that is, that the angle of twist is proportional to the applied torque.

Creating the Axial Force Diagram. The axial force diagram will plot out the internal axial (normal) forces within a beam, column, or cable that is supporting multiple forces along the length of the beam itself. This can be thought of as the internal tension or compression forces. The most relevant practical scenarios that match this description will be main support columns .Circular shaft experiencing an axial torque. A solid, circular cross-sectioned shaft experiences an axial torque T, as shown above.. Angle of twist The hypothesis used in developing the stress and strain in the shaft is that all points on a .
