A compressor weighing 1000 Kg operated at 1500 rpm. When mounted directly to the floor, it produces undesirable vibrations of the floor.
A compressor weighing 1000 Kg operated at 1500 rpm. When mounted directly to the floor,
it produces undesirable vibrations of the floor. To reduce these vibrations, the machine has
to be mounted on a separate concrete block that is separate from the building. The footprint
of the compressor requires that the block be 1.8m wide and 2.2 m long. The soil below the
concrete block has a compression coefficient kc = 20 x 106 N/m3. If the density of concrete
is 23x103 N/m3, then determine the height of the concrete block so that there is an 80%
reduction in the force transmitted to the soil
