- Problem statement: The ladder has a uniform weight of 80 lb and rests against the smooth wall at B. If the coefficient of static friction at A is μ_A = 0.4, determine if the ladder will slip. Take θ = 60°.

Hi. I had a question. Why do we not have a frictional force at point B? If the laws of friction apply, wouldn't it stand to reason that friction would be applied at both points? I am not saying you're wrong, I am just having trouble understanding the reasoning in this case.
we have a smooth wall, so no friction
