At the instant when OP is vertical and AP is horizontal, the link OD is rotating counter clockwise at a constant rate ω = 7 rad/s. Pin P on link OD slides in the slot BC of link ABC which is hinged at A, and causes a clockwise rotation of the link ABC. The magnitude of angular velocity of link ABC for this instant is _________ rad/s (rounded off to 2 decimal places).
The figure shows a wheel rolling without slipping on a horizontal plane with angular velocity 𝜔1. A rigid bar PQ is pinned to the wheel at P while the end Q slides on the floor.
What is the angular velocity 𝜔2 of the bar PQ?
In the configuration of the planar four-bar mechanism at a certain instant as shown in the figure, the angular velocity of the 2 cm long link is ω2 = 5 rad/s. Given the dimensions as shown, the magnitude of the angular velocity ω4 of the 4 cm long link is given by rad/s (round off to 2 decimal places).
A planar four-bar linkage mechanism with 3 revolute kinematic pairs and 1 prismatic kinematic pair is shown in the figure, where AB ⊥ CE and FD ⊥ CE. The T-shaped link CDEF is constructed such that the slider B can cross the point D, and CE is sufficiently long. For the given lengths as shown, the mechanism is
