Q. A four bar mechanism is shown in the figure. The link numbers are mentioned near the links. Input link 2 is rotating anticlockwise with a constant angular speed

ω_{2}

. Length of different links are:

O_{2} O_{4} = O_{2} A = L, A B = O_{4} B = \sqrt{2} L

The magnitude of the angular speed of the output link 4 is

ω_{4}

at the instant when link 2 makes an angle of

90^{o}

O_{2} O_{4}

as shown. The ratio

\frac{ω_{4}}{ω_{2}}

is (round off to two decimal places).

Q. In the four-bar mechanism shown in figure ABC is the coupler link and all the dimensions are in cms. For the configuration shown, AC is aligned with PA while B is aligned with QB. Then the ratio of instantaneous angular velocity of the link QB to that of the link PA is

Q. In the planar mechanism shown in figure the link lengths are given in cm. The ternary link DCE is parallel to the input crank AB. The links BC and EF are parallel to each other at the instant. The slider F is guided in the vertical direction. If the crank AB has an angular velocity of 6 rad/sec, the velocity of the slider is
