Homework Statement
anyone guide me step by step how to use virtual work method to calculate all reactions on this beam?
thanks

have a look at this

A hyperstatic system is a structural system that has more unknown reactions than the number of equilibrium equations available to solve them. This means that the system is statically indeterminate and cannot be solved using traditional methods.
The Virtual Work Method is a technique used to solve hyperstatic systems by considering the work done by external forces and internal forces in the system. It involves breaking down the system into smaller, simpler parts and using the principle of virtual work to find the unknown reactions.
The Virtual Work Method uses the principle of virtual work, which states that the sum of the virtual work done by all external forces acting on a system is equal to the virtual work done by the internal forces in the system. This allows us to set up equations and solve for the unknown reactions in a hyperstatic system.
The Virtual Work Method allows us to solve hyperstatic systems that cannot be solved using traditional methods. It also provides a more accurate solution by taking into account the effects of internal forces on the system. Additionally, it can be used for both linear and nonlinear systems.
While the Virtual Work Method is a powerful tool for solving hyperstatic systems, it does have some limitations. It can only be used for systems in static equilibrium, and it may be more time-consuming and complex compared to traditional methods. It also requires a good understanding of structural mechanics and mathematics to apply effectively.
