I was given the following task:
My problem is the following:
For $A$ and $B$ I’ve got friction forces $R_A$ and $R_B$. I can calculate those by using the formula: $R_A = N_A \cdot \mu $
$\mu $ is given with $0.5$
Now let‘s say the normal force on point $A$ is really high, according to the formula, the friction force should be really high aswell. This does not seem logical for me. Shouldn‘t the friction be only there if the ladder is being push on the ground?
How are those tasks usually calculated?
