A cardboard strip, bent in the shape of the letter C, is put on a rough inclined plane, as shown in the figure.

At what angle of inclination to the horizontal plane will it topple? (assume that it does not slide).

Answer:

Solution:

$y_{c m} = \frac{a}{2}$

$tan (9 0^{\circ} - α) = \frac{y _{c}}{x _{c}} = \frac{3}{2} \Rightarrow tan α = \frac{2}{3}$
