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.

Two forces A and B are applied on an object. If force A is 15 N at 30 degrees North of East and force B is 20 N at 30 degrees West of North. Determine the magnitude and direction of a third force C to be applied on the object that will put it in 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 reactions at A and the forces in the pin at B.

I need the answer as soon as possible

Knowing that the line of action of the force Q passes through point C , derive an expression for the magnitude of Q required to maintain equilibrium.

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?

Take F = 310 N and d = 1.0 m Determine the force in cable AC and AB needed to hold the 24-kg ball D in equilibrium.

The 10-kN and 40-kN forces are  applied to the pins at B and C,  respectively. Calculate the  magnitudes of the pin reactions at A  and F. Neglect the weights of the  members.
