The mechanical tachometer measures the rotational speed n of the shaft by the horizontal motion of the collar b along the rotating shaft. this movement is caused by the centrifugal action of the two 12-oz weights a, which rotate with the shaft. collar c is fixed to the shaft. determine the rotational speed n of the shaft for a reading β = 15°. the stiffness of the spring is 4.5 lb/in., and it is uncompressed when θ = 0 and β = 0. neglect the weights of the links.
