Homework Statement


Hand-drawn diagram on grid paper of a horizontal bar labelled 1 m resting across the tops of two inclined surfaces forming a V shape, with a 90° angle at the bottom vertex and a 53.13° angle marked on the left side.


uk of fraction between bar and both surfaces is 0.2. Bar weighs 5 kg.

i) Is the bar in static equilibrium? If not, which end will fall down and which end will go up?

Homework Equations



F-uk*Fn

The Attempt at a Solution



Not sure how to even begin analyzing this. I cannot visualize the bar moving in either direction first. Any guidance is appreciated.
 
Invent variables for the normal forces at the two ends. (Use different names.) Write the usual horizontal and vertical statics equations for the bar and one for torque. Use a symbol for the angle - don't plug in any numbers until the final equation.
