Question 1
A slider-crank mechanism is used to convert a rotary motion to a translation motion.
Referring to Figure Q1, link BA is rotating counter-clockwise with angular velocity o, and
angular acceleration ã, that causes the slider C to slide horizontally with the velocity ve, and
acceleration āc, as shown.
Given at that instant:
e = 30 degree
B = 60 degree
@ = 6 rad/s
a = 2.5 rad/s
LAn = 0.3 m
0.7 m
(a)
Determine the angular velocity, the angular acceleration of link BC and the velocity
and acceleration of slider C.
(b) If we shorten link BC, is the slider C speed faster or slower? Justify your answer.
