Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.

The rigid bar BDE is supported by two links AB and CD. Link AB is made of aluminum (E = 70 GPa) and has a cross-sectional area of 500 mm^2; link CD is made of steel (E = 200 GPa) and has a cross-sectional area of 600 mm^2.

We are given the statically indeterminate structure in Fig. 1, with a degree of indeterminacy of 2. The value of EI is 5·10^7 kip-in2 for both members. The effect of axial deformations is neglected. You are asked to solve the structure; that is, calculate the support reactions and the internal loading diagrams.
The structure in the figure is composed of two rigid bars (AB and CD) and two vertical rods made of aluminum and steel. All connections are pin joints. Determine the maximum force P that can be applied to the structure if the vertical displacement of its point of application is limited to 6 mm. Neglect the weights of the members.
The flat truss in the figure below is under the action of three external loads P, Q and S, and is supported under pins A and B. The weight of the truss is negligible in relation to the applied loads. Read the following statements and then check the correct alternative. 1)the supports provide exactly the amount of links needed to keep the structure in balance2)the corresponding reactions involve three unknowns that can be determined through equilibrium equations.3)this is a situation where the rigid body is completely bound4)reactions are statically indeterminate which ones are correct?
