Space balance89 in a recently proposed instrument for as tronaut body mass measurement10 the tensile force of a rubber cord is applied to the astronaut under test and the force is measured using a force transducer. The other device is russias body mass measurement device bmmd seen being demonstrated by reid wiseman in this vine he posted last october.
The Best Ways To Measure Body Fat Shape
Space body mass measurement. The slammd is accurate to 05 pounds. Using slammd astronauts can accurately measure body mass with the help of newtons second law of motion fma force is equal to mass times acceleration. The russian body mass measuring device bmmd which uses spring oscillation physics and nasas space linear acceleration mass measurement device slammd which utilizes newtons second law of motion fma. The astronaut rides the bmmd somewhat like a pogo stick and the oscillation of a spring is used to measure mass. The proposed space balance is based on the levitation mass method lmm that was previously proposed and de. Russia came up with a slightly different solution called the body mass measurement.
Currently two types of body mass measurement device are used on the international space station iss. Nasas space linear acceleration mass measurement device slammd used to measure the mass of iss astronauts. To better observe the process skylab carried three mass measuring devices two small ones experiment m074 for measuring the intake and outgo of each astronaut and a large one experiment m172 with an oscillating chair designed for daily monitoring of the weight of the astronauts. Firstly the astronaut has to wrap their legs and body around the device as seen in andrés photo.
