In a structure whose material follows hooke’s law and in which the supports are unyielding and the temperature is constant, what law states that the external virtual work done by a system of forces, P. during the deformation caused by a system of forces, Q, is equal to the virtual work done by a system of forces, Q, during the deformation caused by the P forces.

Bett’s Law

7

Snow loads, wind, pressure suction and earthquake loads and the like are what type of loads?

Environmental Loads

This states that the external effect of a force on a body is the same for all points of application along its line of action, it is independent of the point of application

Principle of transmissibility of a force

9

Among the following axioms of mechanics, which of the following is incorrect?

A set of forces in equilibrium may be added to any system of forces thus changing the effect of the original system.
