The acceleration of a geared system

APPLIED MECHANICS LABORATORY REPORT Title: The speedup of a geared system Aim: To ascend out the hypothesis on the prediction of the doing of rotors connected by gears. Object: The main intent of the experiment is:         To investigate the theory on the prediction of the motion of rotors connected by the gears.         By the locomote burden rule to measure out the inertia on all(prenominal) shaft.         Determine the eq inertia of the system at the appetiser shaft, by the spillage weight method acting. Test rig figure: The hang on of teeth on from each 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 fade body diagrams reveal: P*R=I*a+Tf Should be a straight railway line graph of P*R plotted against a. The intercept should take place the friction torque. Measure the clock taken for the mass to fall through Im then a=2s * m then ?= a (rad/sec^2) t^2 s^2 R Also P=m*g-m*a=m[9.81-a] Nt And for the calculation of goofball of inertia of the system referred to shaft1 we routine: Ieqv= I1+I2*[Na] ^2+I3 [Na*Nc] ^2 Nb Nb Nd Procedure: 1.         Determine, by the falling weight method the moments of inertia associated with each of the individual 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 theoretical instruction 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(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 ...
