Q1) Collar B that has a mass of 12 kg slides on the frictionless arm AA' as shown in figure Q1. The arm is attached to Drum D as can be seen and rotates about point O in a horizontal plane at the rate ở = 0.93t, where ở and t are expressed in rad/s and seconds, respectively. As the arm-drum assembly rotates, a mechanism within the drum releases cord so that the collar moves outward from O with a constant speed of 0.58 m/s. Knowing that at t= 0, r = 0, determine the time at which the tension in the cord is equal to the magnitude of the horizontal force exerted on B by arm AA'.
