Chapter 3: 13. What type of geometric tolerance has no datum features? 14. A theoretically exact dimension is called a 15. The feature symbol specifies that a group of two or more interrupted features of size are to be considered one single feature of size. 16. For an individual regular feature of size, no element of the feature shall extend beyond the maximum material condition boundary (envelope) of perfect form. This statement is the essence of 17. What is the name of the symbol used to identify physical features of a part as a datum feature and must not be applied to centerlines, center planes, or axes? 18. The is the condition in which a feature of size contains the maximum amount of material within the stated limits of size. 19. The total positional tolerance equals the sum of the tolerance and the tolerance.

Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…

Calculate the average fall time and standard deviation using the data above. Average - 1.5s Stdev- 1.85s Use the average fall time and one of the kinematic equations to determine the height of the building. Add the standard deviation from step 1 to the average fall time from step 2. This represents a “maximum fall time.” Use this time to calculate the “maximum” height of the building.
