Explanation Given: Weight of block is 400 lb . Concept used: Apply the Principle of virtual work by providing a small virtual displacement at point C on the system as shown below: The tension in cable will act as an active force id the cable is released. From the above diagram the vertical displacements δ B can be calculated by applying the principle of similar triangle for triangle CEO similarly the displacement δ D can be calculated by applying the principle of similar triangle for triangle ACO. Write the expression for displacement at point B. δ B = 3 5 δ C Here, δ B is the displacement at point B and δ C is the displacement at point C. Write the expression for displacement at point D. δ D = 3 4 δ C Here, δ D is the displacement at point D. Write the expression for virtual work done on system. δ U = − T δ B + W δ D ...... (1) Here, δ U is the total virtual work done on system, T is the tension in cable and W is the weight of block

It is defined as, two or more elements like beams or any two or more force members, which when assembled together, behaves like a complete structure or as a single structure. They generally consist of two force member which means any component structure …

Equilibrium Equations

If a body is said to be at rest or moving with a uniform velocity, the body is in equilibrium condition. This means that all the forces are balanced in the body. It can be understood with the help of Newton's first law of motion which states that the res…

Force Systems

When a body comes in interaction with other bodies, they exert various forces on each other. Any system is under the influence of some kind of force. For example, laptop kept on table exerts force on the table and table exerts equal force on it, hence th…
