The simple mechanism shown in the figure can be calibrated to measure temperature change. Use dimensions of a = 26 mm, b = 88 mm, and L = 166 mm. The coefficient of thermal expansion for member (1) is 20.0 x 10-6/C. Determine the horizontal displacement of pointer tip D of the mechanism shown in response to a temperature increase of 45 C. Assume that pointer BCD is not affected significantly by temperature change. Enter a positive value if tip D displaces to the right; enter a negative value if it displaces to the left.
