The acceleration of a geared system

APPLIED MECHANICS LABORATORY REPORT Title: The acceleration of a geared system Aim: To prove out the theory on the prediction of the feat of rotors machine-accessible by gears. Object: The main end of the experiment is:         To investigate the theory on the prediction of the motion of rotors connected by the gears.         By the locomote slant method acting to guess the inaction on all(prenominal) shaft.         Determine the analogous inertia of the system at the first shaft, by the coin weight method. Test rig figure: The render of teeth on apiece gear: N =90, N =30, N =90, N =90 Theory: In order to evaluate the identical inertia on each shaft by the Falling Weight method. The lead body diagrams reveal: P*R=I*a+Tf Should be a straight delimit graph of P*R plotted against a. The intercept should channel the friction torque. Measure the time 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 haul of inertia of the system referred to shaft1 we call: Ieqv= I1+I2*[Na] ^2+I3 [Na*Nc] ^2 Nb Nb Nd Procedure: 1.         Determine, by the fall weight method the moments of inertia associated with each of the single 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 ...
