The box is on the slope as in the picture. The angle of the slope is
\(\alpha \).
The forces acting on the box are the force of gravity
\(\vec{F_{G}}\) and the
friction \(\vec{F_{t}}\).
The force of gravity can be replaced by two components
\(\vec{F_{1}}\) and
\(\vec{F_{n}}\). (The force
\(\vec{F_{1}}\) is parallel to
the slope and \(\vec{F_{n}}\)
is perpendicular to the slope.) Find \(F_{p}\).
\(F_{p} = F_{G}\cos \alpha \)
\(F_{p} = \frac{F_{G}}
{\cos \alpha } \)
\(F_{p} = F_{G}\mathop{\mathrm{tg}}\nolimits \alpha \)
\(F_{p} = \frac{F_{G}}
{\mathop{\mathrm{tg}}\nolimits \alpha } \)
\(F_{p} = F_{G}\sin \alpha \)
\(F_{p} = \frac{F_{G}}
{\sin \alpha } \)
