Thrc are mtny factors which in 1rncticc affect tllc design of rnncliinc ptrts that canriot cliscrssctl profitally in thc classroom for instancc, cost of construction, capacity of shop lnachinery, etc. lor this reason the teacher must be content if thc student acq11irc.s the p o er to analyzc the forces and the resultant stresses ill machine parts and to apply the proper equations for their design. The illustrations have been carefully chosen to show typical constructions rather than a great variety which tend to confuse the inexperienced student. The standard text books as well as the Arnerican and European technical press have been freely consultctl in the preparation of the manuscript. H. L. NACHMAN. Carcco, Rlarch, 1918.

I U. p it is gradually increased there will be reached a point where if the load is removed the bar does not resume its original form. This oint is called the elastic limit of the material. If the load is still further increased rupture of the material will occur sooner or STRENGTH OF MATERIALS Elasticity. When an external force acts on a rigid body it produces a change of shape in that body. This deformation is called strain. When the force is removcd the body returns to its original shape. This property which cnabIes a body to rcsurne its initial shapc after the appIication of an external forcc is called the elasticity of the material. Load.
