I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m.

Select all the correct statements: a. Moment of force or toque is force multiplied by the perpendicular distance from the point of application of the force to the selected point or center. b. The perpendicular distance is also termed as moment arm. C. The axis of the moments and the planes of the forces are intersecting at the center of the moment. d. Graphically, the moment can also be defined as the area of the triangle formed by joining the center of moments with the ends of the forces. B
