For the assembly shown in the figure, high-density polyethylene bars (1) and (2) each have coefficients of thermal expansion of a = 74 × 10-6/°F. If the temperature of the assembly is decreased by 47 °F from its initial temperature, determine the resulting displacement of pin B. Assume b = 35 in. and 0 = 61°. (1) ☑ Incorrect. Consider a right triangle with one leg of length a and one leg of length b. Determine the dimension a shown in the figure. A B a = B' b' a *u (2) a 16.97 b the tolerance is +/-2% in.
