The nose$-$wheel assembly is raised by the application of a torque M to link BC through the shaft at B$.$ If the arm and wheel AO have a

combined weight of $90$ lb with center of gravity at G$,$ find the value of M necessary to lift the wheel when D is directly under B$,$ at which

position angle theta is $27^($@$).$ The moment is positive if counterclockwise, negative if clockwise. reference picture

Answer: M$=$
