True-False (2pts each). 1. As the pressure angle increases, both the addendum and dedendum dimensions decrease. T/F 2. The diameter of the addendum circle is always slightly greater than the diameter of the dedendum circle. T/F 3. The Lewis bending equation is appropriate for brakes with both short and long lever arms. T/F 4. The Humpage reduction gear train consists of two sets of compound gears. T/F. 5. The gears in an ordinary summer gear set need to have identical modules to mesh properly.T/F. Multiple Choice (2pts each). 6. Which of the following is not a key design consideration for brake materials: a. Cost b. Temperature capacity c. Actuation force capacity 7. The unit polar moment of inertia is helpful in weld design for what reason? a. So that the weld group used in the design can be defined last. b. So that the mechanical load imparted to the structure can be defined last. c. So that the leg size of the weld can be defined last. d. So that the dimension of the structure being welded to a support can be determined last. 8. Spur gears that act as idlers have the following attributes: a. The bending stresses in the teeth are one-way bending in compression b. The bending stresses in the teeth are one-way bending in tensions c. The bending stresses in the teeth are completely-reversed. d. The bending stresses are nominally zero since all of the forces are transmitted from one mating gear to the next. 9. Which of the following is true regarding the stress field in a fillet weld under loading a. Only axial stresses exist throughout the body. b. Only shear stresses exist throughout the body c. A mix of axial and shear stresses exist throughout the body. d. A mix of axial a nd shear stresses exist throughout the body, but for the sake of approximation, only axial stress is considered. 10. Select the best answer regarding a differential band brake drum. a. A the b. band is generally less narrow than the The lever arm can be made of a flexible rubber c. The slack side is connected to the pivat. d. None of the above

Explanation / Answer

1) True - as the pressure angle increases addendum and dedendum circles decreases.

2) True - the diameter of the addendum circle is greater than dedendum circle.

3) False - lewis equation is for gear design

4) True
