The strain energy of the spring when it is subjected to the greatest load which the spring can carry without suffering permanent distortion is known as
A composite spring is made by joining two springs end to end one spring having twice the stiffness of the other. The ratio of the stiffness of the composite spring to that of the stiffness of the two springs could be
When a number of loads rest upon a beam, dflection at any point is equal to the sum of the deflections at the point due to each of the loads taken separately. This statement is known as
If unit loads rest upon a beam at two points A and B, the deflection at A due to unit load at B, equals the deflection at B due to the unit load at A. This is known as
Deflection the point of application of an external force acting on a beam is equal to the partial derivation of the work of deformation with respect to this force
Two shafts of the same material are subjected to the same torque. If the first shaft is of solid circular section and the second shaft is of hollow section whose internal diameter is 2/3 of the outside diameter, the ratio of weights of hollow shaft to solid shaft would be
