The surface of a liquid is just able to support the weight of a six-legged insect. The leg ends can be assumed to be spheres each of radius 3.2 10⁻⁵ ~m and the weight of the insect is distributed equally over the six legs. The coefficient of surface tension in this case is 0.1 ~N / m and the angle of the footfall with respect to the vertical is = / 3 radians (see figure). The mass of the insect is close to
