Question

Determine the horizontal displacement of joint A. AE is constant. Use the principle of virtual work.

Expert Solution

Introduction

In virtual work method, the frame given for analysis is considered to be having unit load in place of applied real load. The forces in members are then calculated for both virtual and real structure.This method is used for displacement of joint carrying load.
