no one here below shows a simple freight elevator in operation hosting loads up and down the side of a building in the same vertical plane the cable of the range practice of a smooth peanut cake a great weight w is suspended at the end of the cable to pass level 21 and threw up in connected at Kay and attached to the vertical wall by smooth pins determine the magnitude and nature of the forces in the to pass when the weight of the crazy is hundred tens and A and B are 40 and 30 degrees respectively ignore the weight of the table of the bus refer​

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
