A 4m rod AB slides down the plane with vA = 4 m/s to the left and aA = 5 m/s2 to the right. Angle θ at this moment is 30o. Determine the angular velocity and angular acceleration at this instant of time.
Angular velocity of AB =( VA-VB)/LAB = (4 cos60 - 0)/4 = 2/4 = 0.5 Insatantaneous centre of rotation is point B since it has zero velocity. Let the angular acceleration be Therefore aA = (AB) = 5 cos60/4 = 5/8
Angular velocity of AB =( VA-VB)/LAB
= (4 cos60 - 0)/4
= 2/4
= 0.5
Insatantaneous centre of rotation is point B since it has zero velocity.
Let the angular acceleration be
Therefore aA = (AB)
= 5 cos60/4
= 5/8
