A bottle has an opening of radius a and length b. A cork of length b and radius (a+Delta A) is compressed to fit into the opening completely (See figure). If the bulk modulus of cork is B and frictional coefficient between the bottle and cork is ? then the force needed to push the cork into the bottle is :

Can a triangle be formed by line segment of lengths a,b and c, such that a=b-c ?

A rigid cylindrical container has inner radius r. A cork having radius r + Delta r and length L is to be fitted so as to close the container. Uniform pressure (Delta P) is needed on the curved cylindrical surface of the cork. Poisson’s ratio of a cork is almost zero, and its bulk modulus is B. (a) Calculate Delta P (b) After the cork is fitted how much force will be needed to pull it out of the container? Coefficient of friction between the container and the cork is mu .
