How is iron primarily excreted from the body? Iron is excreted through urine as a waste product. Iron is eliminated through sweating and skin shedding. Iron is not actively excreted; it is regulated through the absorption process in the intestines Iron is expelled from the body via bile in the liver.

3) A certain machine of mass 400 kg has a shaft that rotates at 1800 rpm. It is known that the machine shows resonance at 1200 rpm. An absorber is to be mounted on top of the machine so that the amplitude of its vibration response with the absorber mounted, within the range 1000-2000 rpm, is less than 50% of its static response measured without the absorber. Here, by static response, we mean the response if the magnitude of the dynamic force were applied statically. Design the absorber. That is find suitable values of absorber mass and stiffness. Hint: Firstly, aim to reduce the amplitude at one frequency, then check the situation at the other frequency. Do this until you find a solution. If you do not think that there is a solution, state it with an acceptable arguments.
