The 950-g gear A is constrained to roll on the fixed gear B. but is free to rotate about axleAD. AxleAD. of length 400 mm and negligible mass, is connected by a clevis to the vertical shaftDE which rotates as shown with a constant angular velocity .ω 1 Assuming that gear A can be approximated bv a thin disk of radius 80 mm. determine the largest allowable value of ω1 if gear A is not to lose contact with gear B.
