Chapter 3, Problem 3P

If the system shown is to be in equilibrium, determine the following: (a) the tension in cable ABC, (b) the force P acting at Hook C, (c) the weight of block A, and (d) the magnitude of the force F. The change in length of Spring 1 is equal to 0.12 ft. Force P is 1/2 the magnitude of the compressive force in spring 2. The compressive force in spring 3, is 1/3 the magnitude of the force in spring 2. The weight of Block G is 1000 lb and the spring constant for all springs is 7000 lb/ft.

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

Question 1: Find the x, y, and z components of reaction at the fixed wall A. The 150-N force is 150 N parallel to the z-axis and the 200-N force is parallel to the y-axis. 2 m 1 m 2.5 m 2 m 200 N

Determine the force P that will keep the pulley system in equilibrium. Neglect the weights of the pullys.

Determine the reactions at A and B.

The two couples act at the midpoints of bars AB and BD. Determine the components of the reactions and the magnitudes of the reactions at A, B and D. Neglect the weights of the members. Draw an FBD of the system as a whole and an FBD of the bar AB, in which you assume the direction of all forces at all pin connections in the positive x and positive y directions for consistency with the options in the questions. Which one of the following equations is NOT one of the equilibrium equations following from the two FBD's?
