Using the figure below, determine a symbolic expression for the magnitude of the

horizontal force F for which mi

does not slip either up or down along the wedge. Assume

all surfaces are frictionless. Express your

answer in terms of some or all of the variables

mi, m2, 6, and the free-fall

acceleration g.

AIdentify forces and draw a free body diagram for the object of interest.

Hint: how

should you orient your coordinate system?

BWrite the x and y components of the applicable Newton's law using the

forces on

your free-body diagram.

CDetermine a symbolic expression for the magnitude of the horizontal force

F for which mi does

not slip either up or down along the wedge.

DCheck the units of your expression.
