[THIRD PART.—FIRST SECTION: ON THE RESISTANCE OF MATERIALS.]

1. Resistance of prismatic bodies to extension and compression. Elasticity of bodies. Modulus of elasticity. Limits of permanent efforts. Resistance to extension and compression of stone, bricks, and analogous materials; also of wood and metals. Applications.

2. Transverse resistance. Some cases in which it is brought into play. Results of experience. Resistance of bodies submitted to the effects of transversal flexure. Results of experience and conventions. Conditions of equilibrium of bodies submitted to efforts directly transversal to their length. Direction and value of molecular efforts. Equation of the axis of the body. Equation of the squaring. Discussion of these equations.

3. Geometrical method for determining the inertia. Application to the research for the inertia of various s. Applications of general equations of equilibrium and of squaring to straight pieces.

1st. A horizontal piece set in a frame at one extremity, and subjected to a weight acting at the other extremity, with a uniform vertical effect.

2d. Horizontal beam placed upon two supports, and subjected to a weight acting at its center, and with a uniform vertical effect.

3d. Beam placed horizontally on two supports, and having two equal weights symmetrically placed with respect to its center.
