WebApr 11, 2024 · When we swim, we talk a little, and then we drift away for a while. Private thoughts in a public place. I turn to face the horizon, swim out to where I can barely see anything else, just horizon and waves, all blue. And then V swims back, and then I’ll swim back too, and once we’re halfway dry, we walk across the grass, and drive home. WebAug 7, 2024 · In a freely-floating body in equilibrium, the centre of buoyancy is vertically below the centre of mass of the floating body. As far as calculating the moment about some axis of the hydrostatic upthrust is concerned, the upthrust can be considered to act through the centre of buoyancy, just as the weight of an object can be considered to act ... maytag washer makes noise on spin cycle https://automotiveconsultantsinc.com
