Question #338369

Two simple clutch disks of equal mass 6.3 kg are initially separate. They also have equal radii of R=0.55 m. One of the disks is accelerated to 5.7 rad/s in time Δt = 1.8 s. They are then brought in contact and both start to sping together. Calculate the angular velocity of the two disks together.

Expert's answer

"M_1=M_2,"

"\\omega_2=\\frac{\\omega_1}{\\sqrt 2}=4~\\frac{rad}s."
