Multiple Choice (2pts each). 6. Which of the following are the considerations for selecting lining materials for brakes? a. Allowable Pressure b. Allowable Temperature c. Allowable Velocity d. All of the above e. a. and b. only 7. Which of the following is not a real method used to speed of an epicyclic gear system a. Tabular Analysis b. Humapge's Gear Reduction Method c. Usage of Relative velocity formulas 8. For two meshing gears, which of the following can be different: a. Tangent Velocity b. Base Circle Diameter c. Diametral Pitch d. Circular Pitch 9. With regard to epicyclic gears, pick the different one. a. Arm b. Carrier C. Pin d. Crank 10. Which of the following differential gear trains uses worm gears? a. Limited Slip Differential b. Torsen Differential c. Conventional Differential e. None of the aboveExplanation / Answer
Answer #6
answer must be e. that is allowable pressure and allowable temperature.
Becuase brake material should be resiste high pressure generated during brake applied . and entire energy (kinetic energy of vehicle) is converted to heat energy. so brake material should withstand such high amount of temperature.
Answer #7
Answer B-- Humapge's gear reduction method
remaining both are used to speed of epicyclic gear train.
Answer #8
Answer is B. Base circle Diameter can be different.
tangent velocity is always same for meshing gear. It is the basis of gear law.
Diametral pitch and circular pitch is related with gear module (module=ratio of pitch circle dia to the no of teeth) Module is always same for meshing gear.
But base circle diameter is only correct option.
Answer #9
Answer is d-- Crank;
All other are available in case of epicyclic gears except crank one.
Answer #10
Answer should be e.
