Consider the cantilever beam as shown. Start with the stress results from mechanics of materials: $\sigma_x = \frac{My}{I}$, $\sigma_y = \tau_{xy} = 0$ Determine the displacement fields u(x, y) and v(x, y). Compare v(x, 0) with the elementary beam solution.

Francis and Bryan are in a heated debate over what fast food chain is better, Chick-Fil- A or Raising Cane's. They decide to end their debate by surveying people on the street to see which fast food chain will earn higher satisfaction scores. They find 25 participants that have never tried either chain and split them up into two groups. They purchase meals from each restaurant for these participants and afterwards give them all a satisfaction survey rated 1-20, with 20 being the most satisfied. The scores for the survey are found below A.what kind of T test should you run? How do you know? B.conduct the appropriate T test and show your work.

Attempt all four questions Unless otherwise stated, all symbols have their usual meaning. Question 1 (a) Two beams, labelled A and B, are shown in Figure Q1a. Each beam is fully constrained at one end and subject to a point load at the other end as shown. Both beams have the same properties and cross-section; however, the beam in A is longer than the beam in B. (i) Reproduce Figure Q1a in your answerbook and clearly indicate on each beam where the maximum tensile stress, maximum compressive stress, and maximum shear stress occurs. (ii) For each of the stresses (tensile, compressive, shear), state which beam experiences the larger magnitude stress. Figure Q1a A F B h F h [8] Question 1 continues on the next page
