+\subsection{Navodilo}
+Na klancu z naklonom $\measuredangle{\alpha}=\ang{\alfa}$ je telo z maso $m=\SI{\njuton}{\kilo\gram}$. Gravitacijski pospešek je $g=\SI{10}{\meter\per\second\squared}$. Koeficient lepenja telesa s klancem je $k_l=\koef$. Kolikšna je največja sila $F_r$, s katero lahko telo vzporedno s klancem vlečemo navkreber, da le-to ne bo zdrsnilo? Kolikšen je največji kot $\measuredangle{\alpha}$, pri katerem brez $F_r$ telo ne bo zdrsnilo?
