Question

For a four bar mechanism as shown in Fig. The lengths of various links are : AD = 150 mm ; AB = 75 mm ; BC = CD = 90 mm. If the link AB rotates at a uniform speed of 120 r.p.m. in the clockwise direction, find the angular velocity and angular acceleration of the links BC and CD with diagram​

Answer 1

and

mark me as brainlist

plz

Answer 2

Explanation:

if ad is 150 mm and ab is 75 mm BC is equal to CD is equal to 90 then BC is equal to 90 and CD are also 90 mm Ab rotated in uniform a speed of 120 RPM then the position of BC is 90 hands upper proved and CD is equal to 90 upper

proved and also given if it rotate clockwise then the change of equation 75 is come on 90 and it came on 115 then because of this ratio b is equal to 150 mm.

hope it may help you
