*17-32. A force of P = 300 N is applied to the 60-kg cart. Determine the reactions at both the wheels at A and both the wheels at B. Also, what is the acceleration of the cart? The mass center of the cart is at G. 30 0.4 m 0.3 m 0.3 m -- 0.2 m 0,08 m

5-67. Due to an unequal distribution of fuel in the wing tanks, the centers of gravity for the airplane fuselage A and wings B and C are located as shown. If these components have weights WA = 45 000 lb, WR = 8000 lb, and We = 6000 lb, determine the normal reactions of the wheels D, E, and Fon the ground. 8 ft F 6 ft 8 ft 6 ft 4 ft 20 ft 3 ft

The mobile crane is symmetrically supported by two outriggers at A and two at B to relieve the suspension of the truck upon which it rests and to provide greater stability. If the truck, crane, and counter-weight have a total mass of 18-tonnes and center of mass at G1, while the boom has a mass of 1.8-tonnes and a center of mass at G2, determine the critical angle where tipping starts to occur when the boom is supporting a load having a mass of 3-tonnes. Plot the total reactions at A and B (in kN) as functions of θ from θ=0° to the critical angle.

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.   (1) If the mass center G is set as the origin (datum), the gravitational potential energy at the state 1 is___  (two decimal places)
