Question: What Is The Relation Between Work Done By External Loads And Work Done By Internal Loads?

How many slope deflection equations are possible if 4 supports are there?

8.

How many sde (slope deflection equations) are possible if 4 supports are there.

Explanation: Each part will give 2 unique equations, so there will be a total of 6 equations.

9..

Which should be avoided in brick masonry?

3. Which of the below should be avoided in brick masonry? Explanation: Vertical joints occur when the end of a brick is in line with the end of the underlying brick, vertically. This would lead to low strength wall as cracks can easily be transferred along these joints.

What should be observed ideally when two bricks are stuck together?

What should be observed ideally when two bricks are struck together? Explanation: It is a test for soundness of brick. A sound brick should not break. It should produce a clear ringing sound.

What is the condition for equilibrium in plastic analysis?

The fundamental conditions of plastic analysis are a) Equilibrium Condition: b) Yield Condition: At collapse, bending moment at any section should not exceed the plastic moment capacity of the beam cross- section.

What is D Alembert’s principle in dynamics?

D’Alembert’s principle of inertial forces D’Alembert showed that one can transform an accelerating rigid body into an equivalent static system by adding the so-called “inertial force” and “inertial torque” or moment. … In textbooks of engineering dynamics this is sometimes referred to as d’Alembert’s principle.

What will be the value of UE if material is linear elastic axial force is increased from 0 to P gradually?

What will be the value of Ue if material is linear elastic? Axial force is increased from 0 to P gradually. Explanation: Due to linear elasticity, we can substitute force in terms of P and Δ and then integrate wrt x to get the final answer.

What is virtual work method?

Virtual work is the total work done by the applied forces and the inertial forces of a mechanical system as it moves through a set of virtual displacements. When considering forces applied to a body in static equilibrium, the principle of least action requires the virtual work of these forces to be zero.

What is the relation between work done and complementary work done?

What is the relation between work done and complementary work done? Explanation: They are equal only when Hooke’s law is applicable i.e. the material is linearly elastic. Explanation: In cases of dynamic load, acceleration may occur and some of the external work will be transferred into kinetic energy.

What will be the external work performed during application of load?

What will be the external work performed during application of load? Explanation: Since loads are gradually applied, work done will be average load times deflection. We can also find by integration. 6.

What is active force diagram?

In physics and engineering, a free body diagram (force diagram, or FBD) is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition. … The body may consist of multiple internal members (such as a truss), or be a compact body (such as a beam).

How do you find virtual work?

The external virtual work is equal to the virtual external force (Pv) multiplied by the real external displacement (Δr) and the internal virtual work is equal to the virtual internal force (pv) multiplied by the real internal deformation (δr).

What is the meaning of virtual?

1 : being such in essence or effect though not formally recognized or admitted a virtual dictator. 2 : being on or simulated on a computer or computer network print or virtual books a virtual keyboard : such as.

Which of the following is true in case of stone brick?

Which of the following is true in case of stone brick? Explanation: Stone brick is very good in compression but weak in tension. … Explanation: Due to its geometry, shear force always comes out to be zero in 3 hinged arches.

What is virtual force?

A virtual force is any system of forces in equilibrium. Example: f(x) and y(x) are real forces and associated displacements. ¯y(x) is a virtual displacement consistent with the boundary conditions.

What are external loads?

External load is defined as the work completed by the athlete, measured independently of his or her internal characteristics [6]. An example of external load in road cycling would be the mean power output sustained for a given duration of time (i.e. 400 W for 30 min).

What is applied load?

A force imposed on an object by a person or another object.

What is the unit of virtual load?

(4.12) will directly provide the displacement of point C due to applied external forces. This method is also known as unit load method. where denotes the internal force in the members due to virtual unit moment applied in the direction of interested .
