Homework Answers
Mean = 20
SD = 3.5
P(X < C) = 0.99
Or, P(Z < (C - 20)/3.5) = 0.99
Or, (C - 20)/3.5 = 2.33
Or, C = 20 + 3.5 * 2.33
Or, C = 28.155

Figure < 1 of 1 Consider, for instance, a bar of initial length L and cross-sectional area A stressed by a force of magnitude F. As a result, the bar stretches by AL (Figure 1) Let us define two new terms: • Tensile stress is the ratio of the stretching force to the cross-sectional area: stress = 5 • Tensile strain is the ratio of the elongation of the rod to the initial length of the bar strain= 41 It...
