1. (a) A structural element is subjected to the stresses σx = a, σy = b, ɩxy = c, where the values a, b, and c are assigned in the table below. i) Write down the stress tensor S corresponding to this stress regime. (1%) ii) Use matrix methods to find the principal stresses acting on this element, using the information in the stress tensor. (6%) iii) Use your results from part (ii) to determine the maximum in-plane shear stress acting on this element. (2%) iv) Use matrix methods to find the direction in which the major principal stress (σmax) is acting. Express your answer as the angle (0) from the current x-axis to the direction of action of this stress. (7%)
2. Calculate the Jacobian matrix of the element shown below. (0,4) (0,0) (2,0) (3,2)
Select the most appropriate answer. O Bemoulli eg was derived by applying Newton's 2nd law to a particle and then integrating along a streamline: while Energy eg was derived using the 1st law of thermodynamics & consequently the Reynolds transoort theorem. Energy eg includes both mechanical.and thermal eneray, while Bernouli eg involves only.mechanical eneray. Bernoulli eg is applied by selecting two.points (can be anywhere) on a streamline (irrotational flow) and then equating terms at those points, while Energy eg is applied by selecting an inlet & on outlet sections and then equating terms at those sections. Energy eg applies to steady. incompressible. viscous flow with additional energies through the pumR. turbine, and heat engines: while Bemoulli eg applies to steady. incompressible, and inviscid flow (h = 0, a = 1). Under special circumstances, Bernoulli eg converts into Energy eg if pump or turbine added along the streamline Bernouli eg was derived by applying Newtan's 2nd law…
