Theory of Machine The relation between number of links (l) and number of joints (j) in a kinematic chain is l = (3/4).(j + 3) l = (2/3).(j + 2) l = (1/2).(j + 2) l = j + 4 l = (3/4).(j + 3) l = (2/3).(j + 2) l = (1/2).(j + 2) l = j + 4 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the anticlockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ + ω₂) r (ω₁ - ω₂) 2r ω₁.ω₂.r (ω₁ - ω₂) r (ω₁ + ω₂) r (ω₁ - ω₂) 2r ω₁.ω₂.r (ω₁ - ω₂) r ANSWER DOWNLOAD EXAMIANS APP
