The engine mechanism shown in Fig. 5 has crank OB = 50 mm and length of connecting rod
AB= 225 mm. The centre of gravity of the rod is at G which is 75 mm from B. The engine
speed is 200 r.p.m.
Fig. 5
For the position shown, in which OB is turned 45° from OA, Find 1. the velocity of G and the
angular velocity of AB, and 2. the acceleration of G and angular acceleration of AB.
• Define coriolis component of acceleration along with its direction. Also derive expression for
it.
The mechanism, as shown in Fig. 3, has the dimensions of various links as follows: AB = DE
= 150 mm; BC = CD = 450 mm; EF = 375 mm. The crank AB makes an angle of 45° with the
horizontal and rotates about A in the clockwise direction at a uniform speed of 120 r.p.m. The
lever DC oscillates about the fixed-point D, which is connected to AB by the coupler BC. The
block F moves in the horizontal guides, being driven by the link EF. Determine: 1. velocity of
the block F, 2. angular velocity of DC, and 3. rubbing speed at the pin C which is 50 mm in
diameter.
What is the implementation circuit for bipolar Return to zero Level or BRZ-L line coding scheme, when binary 1 arrives, it gives + value for first half bit and 0 for the next half bit. when binary 0 arrives, it gives - value for first half bit and 0 for the next half bit.

The y-coordinate of a particle in curvilinear motion is given by y = 4t ^ 3 - 3t where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a x =12t in./sec^ 2 If the ve locity of the particle in the x-direction is 4 in./sec when t = 0 , calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1 sec. Construct v and a in your solution.
