The effect of gyroscopic couple acting on it will be To lower the bow and stern To raise the bow and lower the stern To raise the bow and stern To raise the stern and lower the bow To lower the bow and stern To raise the bow and lower the stern To raise the bow and stern To raise the stern and lower the bow ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A motor car moving at a certain speed takes a left turn in a curved path. If the engine rotates in the same direction as that of wheels, men due to centrifugal force The reaction on the outer wheels increases and on the inner wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on the outer wheels increases and on the inner wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on the rear wheels increases and on the front wheels decreases ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because Bearing centre line coincides with the axis The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor The system is unbalanced Bearing centre line coincides with the axis The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor The system is unbalanced ANSWER DOWNLOAD EXAMIANS APP
