The rod has a diameter of 1 in. and a weight of 10 lb/ft. Determine the maximum torsional stress in the rod at a section located at A due to the rod's weight.
Chemical Tools: Experimentation and Measurement • Recognize the seven basic SI units of measure. • Give the numerical equivalent of the common metric prefixes used with these units. • Express numbers in scientific notation. • Determine the number of significant digits in a measured quantity. • State the result of a calculation involving measured quantities to the correct number of significant digits. • Convert temperatures between the Celsius and Kelvin scales. • Relate density to mass and volume. • Set up and solve problems using dimensional analysis. CHAPTER 1 – The Structure and Stability of Atoms • Give the symbol and name of the first 36 elements of the periodic table. • Identify the group and period to which an element belongs. • Identify the regions of the periodic table (metals, metalloids, nonmetals, alkali metals, alkaline earth metals, transition metals). • Identify properties as physical or chemical. • Identify physical and chemical properties as either extensive or intensive. • Explain the laws of definite proportions, multiple proportions, and conservation of mass. • Show that the law of multiple proportions is obeyed for two different compounds comprised of the same two elements. • Summarize Dalton’s Atomic Theory. • Explain what information about atomic structure was revealed by the experiments of Thomson, Millikan, and Rutherford. • Describe the atom in terms of composition, mass, and volume of the nucleus relative to the mass and volume occupied by the electrons. • Given the symbol for an isotope of an atom or ion, determine the n
