Answer to Question #301065 in Mechanical Engineering for vivek

Question

In the mechanism shown in fig., the crank O2A makes 300

r.p.m in the conte clock wise direction as shown. Find

(i) Angular velocity of link O1A. (ii) Velocity of slider at B.

Answer 1

$V_{OA}=oa=OA*\omega_{AB}$

$=60mm*200rpm$

$=60*10^{-3}*\frac{200}{60}=0.2m/s$

ba =5.6cm*0.1=0.56m/s

BA=8.4cm*2*10=168mm

(i) $\omega_{BA}=\frac{v_{BA}}{BA}$

$=\frac{0.56m/s}{0.168m}=3.33rps$

=$200rpm$

(ii) $v_{BA}=0.56m/s$
