Questions and Answers

What is the mechanical advantage of an inclined plane?

  • Equal to the arctangent of the angle of repose
  • Equal to the ratio of the length of the sloped surface to the height it spans (correct)
  • Equal to the coefficient of static friction
  • Equal to the angle of friction
  • What is the angle of friction, also known as the angle of repose?

  • The angle at which an object will experience maximum acceleration on an inclined plane
  • The maximum angle at which a load can rest motionless on an inclined plane due to friction without sliding down (correct)
  • The angle at which an object will always slide down an inclined plane
  • The angle at which an object will always remain stationary on an inclined plane
  • What is the arctangent of the coefficient of static friction used for in relation to inclined planes?

  • To calculate the work done by friction on an inclined plane
  • To calculate the force required to move an object up an inclined plane
  • To determine the mechanical advantage of an inclined plane
  • To calculate the angle of friction or angle of repose (correct)
