Q1 . Loading on the fishgig from gears and support from bearings is depicted in the figure belowFor this rotating shaftLength of the cheat L 2 .0 mLength of section AB LAB 0 .5 mLength of fraction BC LBC 1 .0 mLength of instalment CD LCD 0 .5 m ?D4 (1 /32 3 .14 (5 10-2 m )4 6 .1328125 10-7 m4Given , Modulus of the shaft material E both hundred 109 Nm-2 (1Where , `g acceleration due to gravity 9 .

8 m /s and ` is level best excursion of the shaftTherefore , supreme deflection ` of this shaft needs to be frontdThis shaft under the given loading and support narrow nookie be seen as dispassionate of a only supported station (Part AC ) and a Cantilever beam (part CDTherefore , one need to calculate maximum deflection in deflection in these dickens split and the high uper of these dickens values can be interpreted as maximum deflection of this shaftMaximum deflection in scarce Supported carry (AC ) portion ?AC ?CDTherefore , for compute essential angular frequence of the shaft ?AC will be usedPutting the value of ?AC in equation (1Natural angulate relative frequency of the Shaft will be radian /s 3628 revTherefore , it can be concluded that critical rpm of the shaft is little than 7200 rpmQ2 . here(predicate) Radial Load L 1000 N revolutions per minute 200Shaft Diameter d 50 mm 5 10-2 mBecause the load and rpm are high therefore , L /d ration should be...If you want to birth a undecomposed essay, dedicate it on our website: Ordercustompaper.com
