Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a D-slide valve Flywheel Meyer's expansion valve Governor D-slide valve Flywheel Meyer's expansion valve Governor ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r₁ = Minimum radius of the cam, r₂ = Radius of the roller follower, and θ = Angle turned by the cam from the beginning of the follower displacement) (r₁ + r₂) (1 + cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) (1 + cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if The center of gravity of the two masses coincides with that of the body All of these The sum of the two masses is equal to the total mass of body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The center of gravity of the two masses coincides with that of the body All of these The sum of the two masses is equal to the total mass of body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at 45° in the direction of rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 90° in the direction of rotation of the link containing the path 45° in the direction of rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 90° in the direction of rotation of the link containing the path ANSWER DOWNLOAD EXAMIANS APP
