Engineering Materials: Structure and properties of engineering materials, phase diagrams, heat treatment, stress-strain diagrams for engineering materials. ‘Velocity of any point on a link with respect to another point on the same link is always perpendicular to the line joining these points on the configuration (or space) diagram.’ Thus, we see from the above equation, that the point ‘c’ on the vector 𝒂𝒃 divides it in the same ratio as ‘C’ divides the link AB on space diagram.
The diagrams show abrupt changes of velocity, which result in large forces at the beginning and the end of the stroke. These forces are undesirable, especially when the cam rotates at high velocity.
The constant velocity motion is therefore only of theoretical interest. () Constant Acceleration.
