cxliv FACULTY OF SCIENCE If the limiting stress of mild steel is 20 tons per square inch and cubic inch weighs 28 lbs how long may round steel bar inches in diameter be in order that it may be just loaded to the limit at the place of maximum stress The bar is suspended from one end and is supporting its own weight bar of mild steel is 20 feet long and square inches in section the limit of elasticity is 20 tons and its modulus of elasticity 14 000 tons Calculate Resilience per cubic inch of material Total Resilience Show how the formula you use is obtained It is known that bar square inch in section may safely carry load of tons What must be the area of bar feet long which can be safely used to check load of 000 lbs falling feet What is Poisson's Ratio How mas its value for given bar be determined without directly measuring lateral contraction State yh&t you know regarding experiments on the effects of repeated load how would your knowledge of these experiments influence you in fixing the factor of safety in designing connecting rod What is Gordons formula for struts and how is it obtained State the effect which the method of fixing the ends of strut has on the buckling load cast iron column is to be of circular section and 15 feet long What must be its diameter in order that it may safely carry load of 20 tons when the ends of the column are flanged and bolted Factor of safety Sketch diagrams of shear force and bending moment and state in each case their maximum value for the beams of which particulars are given Beam feet long built into wall at one end and loaded at the other with load of lbs Same beam but uniform load of lbs per foot run Beam feet long supported at the ends and loaded at the middle with load IF lbs
