Question

Find the force P that must be applied in order for the mechanism shown in the figure to remain in balance at the β angle, using the virtual works method. The mass per unit length of each bar is m.

Expert Solution

Step 1

Principle of Virtual Work:

When a particle is acted upon by a set of forces in static equilibrium, we may impart to the particle a virtual displacement consisting of a translation of the particle in any direction. During this virtual displacement, the virtual work done by the forces must be zero because the forces are in equilibrium.

Consider the figure shown below:
