The stiffness of a beam of rectangular cross section is proportional to the breadth and the cube of of the depth. If the breadth is 20 cm., express the stiffness as a function of the depth.


Sagot :

let s = stiffness
     b = breadth
     d = depth

s = bd^3

just substitute the given value for breadth:

s = 20d^3   ans...
