Supply 5 n∙m of torque to a bolt located at the origin using a wrench that lies along the positive yy-axis. assume the bolt head is at the origin and the threaded portion of the bolt lies along the negative xx-axis. if you apply a 25 n force at the end of the wrench in the direction − what length of wrench would be required to supply the desired torque? under this force are we tightening or loosening the bolt?

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)
