i was wondering if anyone could help me with this problem i got for homework. i'm not completely sure where to start with this, so any advice is appreciated. the closest problem i've done with this is just finding the angular velocities and accelerations of the other rods, and i don't know if its the weights thrown in there that is confusing me, but again, any help is appreciated. The pins in the system shown are currently located at the following coordinates (in meters): A: (0,0); B: (0,1) ; C: (1,0); D: (0.5,0). Rod AB always rotates at 0.5rad/s CCW and accelerates at 0.1rad/s2 CW. Rod CD rotates at a constant 2 rad/s CCW. The collar has a mass of 1200grams. BC is one rigid body with mass of 2kg and radius of gyration of 0.3m. a. Through what angle (radians) will AB have rotated after 42 seconds? b. What are the accelerations and net forces on the collar at this instant? Show all steps. c. What is the net moment applied to BC about its center of gravity?
