Mechanical Engineering > GATE 2022 SET-2 > Impulse
A rigid homogeneous uniform block of mass 1 kg, height h = 0.4 m and width b = 0.3 m is pinned at one corner and placed upright in a uniform gravitational field (g = 9.81 m/sยฒ), supported by a roller in the configuration shown in the figure. A
short duration (impulsive) force ๐น, producing an impulse ๐ผF, is applied at a height
of ๐=0.3 m from the bottom as shown. Assume all joints to be frictionless. The
minimum value of ๐ผF required to topple the block is
Correct : b
