Rod OA rotates countert.lockwise with an angular position & 2t rad, where t is in seconds. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other collar slides over the cincular hoop md descrrbed by the equation r= 16 cost m. IL the total masof the both collars is 0.5 kg, detemine the force which the circular bop rod exerts on one of the collars and the force that OA exerts on the other collarat the instant 0= 30Motion is in the VERTICAL plane, 0-021
