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 Slightly more than 95 mm 45 mm Slightly less than 95 mm 95 mm Slightly more than 95 mm 45 mm Slightly less than 95 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, the fixed instantaneous centers are those centers which Remain in the same place for all configurations of the mechanism Vary with the configuration of the mechanism Moves as the mechanism moves, but joints are of permanent nature None of the listed here Remain in the same place for all configurations of the mechanism Vary with the configuration of the mechanism Moves as the mechanism moves, but joints are of permanent nature None of the listed here ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In considering friction of a V-thread, the virtual coefficient of friction (μ₁) is given by μ₁ = μ/sin β μ₁ = μ sin β μ₁ = μ cos β μ₁ = μ/cos β μ₁ = μ/sin β μ₁ = μ sin β μ₁ = μ cos β μ₁ = μ/cos β ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will change Will not occur Will remain same Could change or remain unaltered depending on which link is fixed Will change Will not occur Will remain same Could change or remain unaltered depending on which link is fixed ANSWER DOWNLOAD EXAMIANS APP
