Abstract: | Here are three samples of results. (1) Let m be a finite (absolutely) continuous mass distribution in ℝ2, and let ℓ = {ℓ1, ..., ℓ5 ⊂ ℝ2} be a quintuple of rays with common origin such that any two adjacent angles between them make a sum of at most π. Then an affine image of ℓ subdivides m into five parts with any prescribed ratios. (2) For each finite continuous mass distribution m in ℝn, there exist n mutually orthogonal hyperplanes any two of which quarter m. (3) Let m and m′ be two finite continuous mass distributions in ℝRn with common center of symmetry O. Then there exist n hyperplanes through O any two of which quarter both m and m′.
