Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) sinφ + sinα = b/c cosφ - sinα = c/b cotφ - cotα = c/b tanφ + cotα = b/c sinφ + sinα = b/c cosφ - sinα = c/b cotφ - cotα = c/b tanφ + cotα = b/c 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 clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ + ω₂)r (ω₁ - ω₂)r (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ + ω₂)r (ω₁ - ω₂)r ANSWER DOWNLOAD EXAMIANS APP
