Hey, I'm having trouble with an equilibrium problem different than the ones I've previously done. Partially because I can't seem to find the clockwise/counterclockwise forces to balance.(adsbygoogle = window.adsbygoogle || []).push({});

Question:

A uniform ladder has a mass of 16kg (156.8N) and a length of 8.5m. It stands on the ground and leans against a vertical wall, making an angle of 62 degrees with the ground. The friction between the ladder and the wall is not significant. What is the smallest force of friction between the ladder and the ground which will just prevent the ladder from slipping?

Currently I have:

(156.8N)*(4.25m)*(sin62)

and I dont know where to go from there or if that is even how I should start.

Thanks,

Noah Jordan
