工字梁

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam. In front of the engine ((e)ng1), Gitta Giraffe (gu) is doing some hard work: She's stacking a capacitor (二) on a dinosaur bone (丨) on a capacitor (二). She's not very successful, but then she gets the idea to use steel beams (工) as support.

字 = 子 + 宀 : Zorro got a new task from mission control: he is to have an egg standing on its tip. Zorro thinks smart and remembers the egg of Columbus, so he puts the egg in a graduation cap as egg cup and ditches one end of the egg with a huge printing letter. Unfortunately the egg wasn't boiled and there is no gravity, so he messes up the whole bathroom. Mission control can't stop laughing since all they wanted was to fool Zorro into this trick.

梁 = 氵 + 八 + 刀 + 木 : Li Qingzhao (li) wants to repair the anglepod's kitchen (ang2), specifically, she wants to set up a new beam on the roof (梁). To reach her goal she puts the lower end of a Christmas tree (木) into a broad water bottle (氵) so that it stands steady. She then proceeds to chop off all the branches with a cleaver (刀), so she can obtain the beam. As she lifts the beam onto the walls, she pushes off an eight ball (八), which falls down and crashes the water bottle (氵). Fortunately she won't need the water bottle anymore since she already put up the beam of the new roof (梁).
