Angular oscillation of the slotted link is achieved by the crank OA, which rotates clockwise at the steady speed N = 118 rev/min. Find the angular velocity of the slotted link when θ = 61°

The angular velocity is 4.939rad/sec

Explanation:

θ = 61°

N = 118 rev/min

The formula for angular velocity is given as;

w = θ/t

where;

w = angular velocity

θ = angle

t = time in rad/sec

1 rev / min = 0.1047 radian/second.

Therefore 118 rev/min = 118*0.1047rad/sec

=12.35rad/sec

Substituting into the formula, we have

w = 61/12.35

w = 4.939rad/sec

Angular velocity will be 65.3 rad/s
