Strength of the Thin-plate Beam. 



Assume for the purpose of our calculation E =13,500 tons, 

 and take m= '1. 



From (I.) we get Q = -385. 



From (II.) we get by the aid of (I.) :— 



D =

Thickness of plate in inches. 



From (III.) we get : — 



Bending-moment at c — -2071. 

 Therefore : —

„ bending '= r 2 = 15 - 216 tons/in. 2 



Maximum tensile stress = 16*14 tons/in. 2 

 „ compressive „ = 14*29 tons/in. 2
