Required information of 2 Channel AB is fixed in space, and its centerline lies in the xy plane. The plane containing edges AC and AD of the channel s parallel to the xz plane. The surfaces of the channel are frictionless and the sphere Ehas 1.9 kg mass. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. F B ences E D C 30* /A $30 N Determine the force supported by cord EF, and the reactions Rc and RD between the sphere and sides C and D, respectively, of the channel. (Round the final answers to four decimal places.) The force supported by cord EF is IN. The reactions RC and RD between the sphere and sides C and D, respectively, of the channel are as follows: RC= RD =
