الصفحة 68 - ... is inversely proportional to the square of the distance of the point from the source.
الصفحة 323 - Fig.188. tively to the other. Such a stress is called tangential or shearing stress, being the stress called into action by shearing. Let us return to the case of the stretched bar carrying a load P (Fig. 138). On a transverse section of the bar only a normal stress is produced. Now suppose we take an oblique section, whose normal makes an angle 6 with the axis of the bar, and let us resolve the force P into two components, one perpendicular and the other parallel to the section. The normal component...
الصفحة 507 - Intensity. — The word STRESS has been adopted as a general term to comprehend various forces which are exerted between contiguous bodies, or parts of bodies, and which are distributed over the surface of contact of the masses between which they act.
الصفحة 221 - F/Xis called the co-efficient of friction and will be denoted by /. The value of / depends on the nature and condition of the surfaces in contact, whether rough or smooth, dry or lubricated. Under certain circumstances and within certain limits it is independent of the area of the surfaces in contact and of the velocity of sliding. These statements may be called the " ordinary " laws of friction. The evidence on which they rest and the limitations to their truth will be considered hereafter; for...
الصفحة 287 - The moment of inertia of an area about any axis is, therefore, determined by adding to the moment of inertia of the area about a parallel axis through the centre of gravity the product of the area into the square of the distance between the two axes.
الصفحة 512 - Force is an action between two bodies, either causing or tending to cause change in their relative rest or motion.
الصفحة 485 - This is expressed in formal terms by the annexed statement of the SECOND LAW of Thermodynamics. Heat cannot pass from a cold body to a hot one by a purely self•acting process. (Clausius...
الصفحة 419 - Columns A give the power of the speed to which the resistance is approximately proportional ; columns B give the mean resistance per square foot of the whole surface of a board of the lengths stated in the table ; columns C give the resistance of a square foot of surface at the distance sternward from the cutwater stated in the heading.
الصفحة iv - What are the conditions of a science? and when may any subject be said to enter the scientific stage ? I suppose when the facts of it begin to resolve themselves into groups ; when phenomena are no longer isolated experiences, but appear in connection and order ; when, after certain antecedents, certain consequences are uniformly seen to follow ; when facts enough have been collected to furnish a basis for conjectural explanation, and when conjectures have so far ceased to be utterly vague, that...
الصفحة 520 - If the beam be fixed at one end and loaded at the other, there will be shearing as well as bending on all sections.
