The acceleration of a geared system

APPLIED MECHANICS LABORATORY REPORT Title: The acceleration of a geared corpse Aim: To jump step forward the surmisal on the prediction of the motion of rotors connected by gears. Object: The main object of the experiment is:         To investigate the theory on the prediction of the motion of rotors connected by the gears.         By the locomote weight method to evaluate the inertia on all(prenominal) shaft.         Determine the equivalent inertia of the system at the catechumen shaft, by the fall weight method. Test rig watch: The add of teeth on from to each one one gear: N =90, N =30, N =90, N =90 Theory: In order to evaluate the equivalent inertia on each shaft by the Falling Weight method. The melt automobile trunk diagrams reveal: P*R=I*a+Tf Should be a straight line graph of P*R plotted against a. The intercept should give the friction torque. Measure the clock taken for the mass to fall through Im then a=2s * m then ?= a (rad/ southondment^2) t^2 s^2 R Also P=m*g-m*a=m[9.81-a] Nt And for the calculation of snatch of inertia of the system referred to shaft1 we exercising: Ieqv= I1+I2*[Na] ^2+I3 [Na*Nc] ^2 Nb Nb Nd part: 1.         Determine, by the falling weight method the moments of inertia associated with each of the idiosyncratic shafts. 2.         Assemble the system so that the gears meshed. 3.         Determine by the falling weight method the equivalent inertia of the system at the fist shaft. 4.         Compare the equivalent inertia with the theory-based development the equation: Sample Calculations: M=F = 1=0.101 Kg g 9.81 a=2s= 2*1 =0.0154 m/sec^2 t^2 11.38^2 P=m(9,81-a)=0.101*(9.81-0.0154)=0.999 Nt P*R1= 0.999*0.019=0.0190 Nt*m ?= a = 0.0154 =0.8105 rad/sec^2 R 0.019 Table of results: Shaft 1 R=0.031 m S=1 m W(Nt)         t(s ec)         a(m/sec^2)  Â!  Â Â Â Â Â Â P(Nt)         Pr(N*m)         ?(rad/sec^2) 1         11.17         0.016         0.999         0.031         0.517 2         6.99         0.041         1.993         0.062         1.322 3         4.51         0.098         2.972 ...
