## The four-bar linkage supports the homogeneous box of weight W. Neglecting the weight of the linkage, determine the horizontal pin reactions at A and B.

To determine

Horizontal pin reaction at point A and B

### Explanation of Solution

Given information:

Virtual work δU done by force F is defined as:

δU=F.δr=Fcosαδr

In above equation

F - Force

δr - Virtual force

α - Angle between F and δr

Virtual displacement δrB of point B is defined as:

δrB=rABδθ

In above equation

δθ - Virtual rotation

rAB - Magnitude of vector drawn from A to B

Calculation:

The length xB

xB=bsinθ

The virtual displacement δxB

δxB=bcosθδθ

The length yB

yB=(2a+b)cosθ

The virtual displacement δyB
