Determine the reactions at A and the tension in the string. The support at A restricts all translations and only the rotations about the y- and z-directions. The 20° angle for the force F applied at E is in the x-y plane, and the 30° angle is a rotation down towards the negative z-direction from the line ED. The magnitude of the applied force is [F] = 100N, and all distances shown are in meters. (35 points) A (2,0,0) 45° 30% Z X E (0,1,0) 30⁰ 20% D F=100N Problem 2. The coefficient of friction is u = 1/2 for the right end of the bar in contact with the horizontal floor. The contact between the left end of the bar and the inclined surface is frictionless. The man of weight W begins at the bottom of the bar and his feet do not slip as he walks upward. The length of the bar is L, and the bar is weightless. Determine the distance x that the man can walk along the bar before it slides. (25 points) C (1,3,2) B (0,5,0) y Determine the reactions at A and the tension in the string.
