Question
An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rope makes an angle 6 with the plane, then
the magnitude of the force is
μW
F =
µ sin(8) + cos(0)
Where u is a positive constant called the coefficient of friction and where 0 < 0<T/2. Find the value for tan 6 which minimizes the force. Your answer may
depend on W and 4, but use "u" instead of uwhen entering your answer.
tan 0 =
