A 400-lb weight is attached at A to the lever shown. The constant of thespring BC is k = 250 lb/in., and the spring is unstretched when θ =0.Determine the position of equilibrium.

27- O A) -2/7 B) -3/7 C) -4/7 D) -5/7 O E) -6/7

If the mass of the girder is 4.6 Mg and its center of mass is located at point G, determine the tension developed in cable BC for equilibrium. Supply the answer in kN. 45 B FAB G 30° D

2. Determine the tension of AB, AC, and AD for equilibrium.

Three cables (AD, BD and CD) are connected at D, which support the 450 lb cylinder W. Determine the tension in each cable for equilibrium. Compute the forces in lb but do not enter units in your answers. Report 3 significant figures. 6 ft 4 ft A O D B W C -9 ft- 12 ft 5 ft y

When holding the equilibrium, the humorous H, assumed to be smooth, exerts normal forces Fc and FA on 6- 15-lb stone in the radius C and ulna A as shown. Determine B these forces and the force Fg that the biceps B exerts on the radius for equilibrium. The stone has a center of mass at G. Neglect the weight of the arm. H FB 75° Fo 0.8 in. FA 2 in. 14 in.

The vertical mast supports the 6.1-kN force F and is constrained by the two fixed cables BC and BD and by a ball-and-socket connection at A. Calculate the tension T1 in BD. Can this be accomplished by using only one equation of equilibrium? Assume a = 4.6 m, b = 3.6 m, c = 1.8 m, h = 4.9 m. В h T1 T2 F. b kN Answer: T1 = i

Two forces F1 150 N and F2 50 N to hold the weight of 200 N. Check and determine if the body is in equilibrium or otherwise. If it's not in equilibrium then in which direction how much force F3 shall be applied to make the frame in equilibrium. While F3 cannot make angle greater than 45° with x-axis. F3 y B 40° 200 N

The compound bar is supported by a thrust bearing at A, a slider bearing at B, and the cable CD. Determine the tension in the cable and the magnitude of the bearing reaction at A. Neglect the weight of the bar.
