Problem (4.2): A lunar soil sampler consists of a tubular shaft that has an inside diameter of 45 mm and an outside diameter of 60 mm. The shaft is made of stainless steel, with a shear modulus G = 80 GPa. In Figure (4.23), the sampler is being removed from the sampling hole by two 150-N forces that the astronaut exerts at right angles to arm DE and parallel to the lunar surface. Assume that the external torque that is exerted by the soil from A to B is uniformly distributed, with magnitude to. (a) Determine the maximum shear stress in the shaft of the sampler tube AC, and indicate the location (s) where it acts. (b) Determine the angle of twist of end C with respect to end A, that is, determine:

MATLAB

MATLAB software is a registered trademark, multi-model programming language, and numerical computing environmental system created by MathWorks. 'MATLAB' is the short-form of "Matrix Laboratory". The MATLAB software permits the utilization of matrix operations, graphical representation of data, execution of algorithms, development of user interface, and linking programs created in other languages. Even though MATLAB is developed mainly for numerical computing, there is an optional toolbox that uses a symbolic engine known as MuPAD giving access to all the symbolic computing abilities. In addition to this, a Simulink package delivers graphical multi-domain simulation and design that is model-based for embedded and dynamic systems. MATLAB users are spread worldwide across the world and use MATLAB extensively.
