Question

The two block diagram realizations, depicted in the figures, of a spring-damper-mass system are equivalent: у y y Uin(t) 1/M y(t) X2 X2 X1 X1 B. tk у y(t) - 1/M X2 x X1 D. B True False

Answer 1

for the block : diagram. YCH Vinit). y 14 5 퍼 3 24 B +15+ diagram Now we know that block diagram reduction technique. - 4077 CCS) C() gost GO .will be so the block dic diagram yet). - h Bling from. Block di the diagram technique the block diagram is false. Now we can very by finding transfer function, use of Mas on loop gain formula. formula is yes) for ward Path gain - sum of loop gani so for 1st block diagram. ve LxIx v(s). 1 Ms² + A STK Vest m S S 1 + B + ms MS2

Now from the block diagram of 2nd. ㅗ yo R M 워 { 우우기부 S 1 +3+ x 52 S - 씬 ms2 94 BS+K yhtsant & W s2
so here false
