Expert Solution

Step 1 Introduction

Influence Line Diagram :ILD is a quick and easy way to discover all of this as quickly as possible and wherever you want in the amount of time taken into consideration. This method is most useful in entrance exams where time is the most important factor. Since you can easily spot the reactions, S.F. & B.M. as quickly as possible to make efficient use of your precious time.
When direct or impact loads move across spans or structures such as road bridges, mobile cranes in industrial buildings, etc. will produce different reactions, shear forces and bending moments for their different positions. Any structure or structural element should be designed under the most severe stress conditions that can occur on the structure. The structural designer discovers the load locations that produce the greatest stress in and can be determined by the influence line diagram.
