The acceleration of a geared system

APPLIED MECHANICS LABORATORY REPORT Title: The acceleration of a geared constitution Aim: To jump start 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 fledgling shaft, by the fall weight method. Test rig attend: The add of teeth on individually gear: N =90, N =30, N =90, N =90 Theory: In order to evaluate the equivalent inertia on distributively shaft by the Falling Weight method. The melt soundbox 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 time taken for the mass to fall through Im then a=2s * m then ?= a (rad/ irregular^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 intent: Ieqv= I1+I2*[Na] ^2+I3 [Na*Nc] ^2 Nb Nb Nd agency: 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 suppositional development the equation: Sample Calculations: M=F = 1=0.101 Kg g 9.81 a=2s= 2*1 =0.0154 m/ south^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(sec)         a(m/sec^2)         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 ...
