大势所趋

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

势 = 力 + 执 : The space station's scientists want to conduct an experiment in the space station's bathroom (Ø4) to find the momentum (势) and potential energy (势) of a pendulum in zero gravity. Everything is already set up, they just have to push the power button (力)—but Sherlock Holmes (sh) insists on seeing their license (执) first before he allows it.

所 = 戶 + 斤 : Susan Saint Bernard and her whole family are weight lifting in the place of the observatory. They are all together lifting one barbell.

趋 = 刍 + 走 : Cupid (qu) loves to do Nordic walking (走) in front of the space station (Ø1), but today he has to move a lot faster (趋) than usually, otherwise the gardener will catch him with his lawn mower (刍).
