Question

In order to make a elastomeric bearing act/ function as a soft spring it should be made to allow it to bulge laterally and also the stiffness compression can be increased by simply increasing the limiting amount of the lateral bulging.

(a) True

(b) False

I got this question by my school teacher while I was bunking the class.

The above asked question is from Finishing Work in portion Rules and Methods of Measurement of Civil Engineering Drawing

Answer 1

Correct answer is (a) True

Explanation: In many cases in order to increase the compression stiffness of the bearing the usage of metal plates is made. Once steel plates are included in the bearings the freedom of the bulge is restricted dramatically, also the deflection of the bearing is reduced as compared to a bearing without the presence of steel plates. The tensile stresses of the bearings are induced into the steel plates. But the presence of the metal plates does not affect the shear stiffness of the bearings.
