Velocity and accleration diagrams

In summary, when drawing velocity and acceleration diagrams for a slider crank or slotted crank mechanism, we must consider the two components - tangential and radial component. The tangential component should be drawn perpendicular to the radial component, but the direction of the perpendicular is dependent on the conventions followed, which may involve clockwise or counterclockwise directions. This can be confusing, so it is important to thoroughly understand the concepts before attempting to draw the diagrams.

how do we go about deciding the directions while drawing the velocity and accleration
diagrams for a given slider crank or slotted crank mechanism.while drawing the accleration
diagrams,2 components -tangential and radial component need to be shown ,so
when we draw the tangential component perpendicular to the radial component,in which direction would we take the perpendicular?please tell me, as while drawing it is really confusing

Sorry buddy, my answer ll offer you no direct help.:redface:

That subject takes hell of a time to understand. Just keep reading & try to resolve your concepts, it gets easy afterward

but please ,let me know the conventions i need to follow while dealing with
this topic-it has so many directions-clockwise,counterclockwise.
 

Related to Velocity and accleration diagrams

1. What is the difference between velocity and acceleration diagrams?

Velocity and acceleration diagrams both represent the motion of an object, but in different ways. A velocity diagram shows the rate at which an object is changing its position, while an acceleration diagram shows the rate at which an object is changing its velocity.

2. How are velocity and acceleration diagrams related?

Velocity and acceleration diagrams are related because acceleration is the derivative of velocity. This means that the slope of a velocity diagram at any point represents the acceleration at that point.

3. What are some common applications of velocity and acceleration diagrams?

Velocity and acceleration diagrams are commonly used in physics and engineering to analyze the motion of objects. They are particularly useful in understanding the movement of complex systems, such as vehicles or machines.

4. How do you interpret a velocity or acceleration diagram?

A velocity diagram is read from left to right, with the horizontal axis representing time and the vertical axis representing velocity. The slope of the curve at any point represents the acceleration at that point. An acceleration diagram is read in a similar way, with the slope of the curve representing the change in acceleration over time.

5. What factors can affect the shape of a velocity or acceleration diagram?

The shape of a velocity or acceleration diagram can be affected by a variety of factors, including the initial velocity of the object, external forces acting on the object, and the object's mass and shape. Friction and air resistance can also impact the shape of these diagrams.
