## Introduction:

First of all, you should know what is dynamics of machines or machinery. The subject Dynamics of Machines (DOM) are derived from the "Theory of Machines". Let me explain it. Theory of Machines is the science which deals all related to machines. That is, displacement, velocity, acceleration, various forces acting on the machine parts and their effects are studies. From which some of the specific studies have been made and those are termed into different subcategories. DOM is such one. So the classification of Theory of Machines can be understood from the following diagram.

Dynamics deals with the study of forces and their motions of parts of machines, wheres as Kinematics deals with only the study of the motions (displacement, velocity and acceleration analysis only). So you may think what is kinetics. Kinetics is the science which deals with only the study of inertia forces and their effects. Now what should be the statics? It is simply defined as the study of body or machine parts under the rest (No external forces are acting)

## Some basic terminologies involved in the study of Static force analysis of mechanisms

Before going into analysis section, you must know,
• What is static force?
• What is dynamic force?
• What is inertia force?
Static Force: It is nothing but a force which is experienced due to the self weight or load of a body or parts of machine. Example: Hanging weights

Dynamic Force: It is a force that are found in the moving parts of a machine. Moving can be linear, rotation or some other means. Example: Forces in the rotating fan, prime movers, lathe in operation, drilling machines in operations and so on.

Inertia Force: It is an imaginary internal force of body which is created due to the rotating or reciprocating parts of a body.  It resists any change in the status of motion of body. It has the tentency to keep the moving objects in a straight line. Ex: Moving cricket ball

Equilibrium: A body is to be in equilibrium when all the forces are in balance and no resulting acceleration presents in it.

Static Equilibrium: When a body is at rest, it tends to remain at rest. So there is no velocities. This status is called as static equilibrium. That is the body is statically balanced.

Dynamic Equilibrium: When a body is in motion, it tends to keep the motion. So the velocities exist but remains constant. This status is know to be dynamic equilibrium

Newton's first law of forces: Static and dynamic equilibrium are defined based on the newton's first law of motion. The law states that every body continues its state of rest or motion unless it is compelled to change its state by externally applied force.

Conditions for equilibrium: There are two conditions defined for equilibrium whether static or dynamics equilibrium.
1. Vector or algebraic sum of all forces acting on a body must be zero
2. The Vector or algebraic sum of all the moments of all forces about any point must be zero.
Mathematically, ΣF = 0, ΣM = 0, where F is resultant force, M is resultant moment

In case of planer mechanisms, the forces are being solved along two mutually perpendicular axes. So the equation are, ΣFx = 0, ΣFy = 0, ΣFM= 0

## Example for equilibrium - Equilibrium of two and three forces systems

Let us consider a body with two force system as shown in the Figure 1 and 2.

Here, consider two forces of different magnitude and action at different directions as shown in the figure. Since two forces are not equal and in different directions, the vector of sum of these forces will not be zero and hence they will be not in equilibrium. So a body under the action of forces will be in equilibrium when
• Two forces must be equal in magnitude
• They should act along the same line and in opposite direction to each other
These conditions are satisfied in the Figure 2 shown below and hence the forces in it are said to be in equilibrium.

Similarly, for a body under the action of three forces, the equilibrium status will be governed by the following rules,
• The resultant force of three forces must be zero
• The line of action of all the three forces must be meeting at a common point called as the "point of concurrency"

The respective figures are shown below.

Note: Moment about a point can be defined as the turning effect of a force about that point. It is measured using magnitude of force x the perpendicular distance between the force and the point.

## Free Body Diagrams

It can defined as the diagram which describes various parts of machines or mechanisms that are physically disconnected.. Each part or link will be in equilibrium when the whole system in equilibrium. F.B.D is an important toll in analyzing the forces in mechanisms. See the following example in which the all links are freely drawn by disconnecting from each other in a four bar mechanism.

## Methods of Static Force Analysis of Simple Mechanisms

There are generally three methods of the static force analysis. There are:
1. Principle of Super position
2. Method of normal and radial components
3. Principal of virtual work
Let's see each method one by one.

Directions—(Q. 36 to 50) Read the following passage carefully and answer the questions given below it. Certain words / phrases have been printed in bold to help you locate them while answering some of the questions. A man called Ramaya lived in a small village. Despite being a nice man, he did not have any friends. It was well known in the town that anyone unfortunate enough to look at him first thing in the morning would not be able to have food that day. That was why no one in the town liked encountering Ramaya in the morning, if they could help it. As soon as the king heard this rumour he decided to try it out himself.

He summoned Ramaya to the palace and ordered him to sleep in a room adjacent to his bedchamber. Ramaya had no choice but to follow the king's order. He feared that the rumour would come true. The next morning, the first thing the king did after waking up, was to take a look at Ramaya. When the king reached the breakfast table, he saw thatthe royal chef had forgotten to prepare his favourite dish. This
angered him and he refused to have breakfast. After finishing a few important duties in the court, the king went to the dining hall for lunch. The food arrived piping hot. The king had hardly picked up the
first morsel when he caught sight of a fly in the food. He left the table in disgust and when the food was prepared again for him, he found that he had lost his appetite. At the dinner table, an ignorant minister started eating before the king had started. This offended the king. He stormed out of the dining hall and refused to come back. As a result, the king could not eat anything at all that day. The enraged king was now convinced that Ramaya was really jinxed. He ordered that Ramaya be hanged. In those days the king's word was the law. The soldiers had no option but to take Ramaya to the gallows. While on their way to the gallows, they met the court jester. He heard the story from Ramaya. The jester felt that it was an unfair decision and that none of this was Ramaya's fault. He came up with a plan to save Ramaya from being hanged. He whispered something in Ramaya's ears. Ramaya nodded before being whisked away.

It was mandatory to grant one last wish to the person who was being hanged. When the soldiers asked Ramaya about his last wish, he asked them to convey a message to the king. He also requested that he be hanged only after hearing the king's response. "Tell the king that while it may be true that anyone who sees my face first thing in the morning does not get anything to eat that day, it's also true that if
anyone sees the king's face first thing in the morning, as I did, he has to lose his life. So who's the greater jinx - the king or I ?" said Ramaya.

On hearing the message, the king was stunned. He realised his foolishness and ordered his soldiers to stop the execution. He summoned Ramaya and offered him gifts. He also requested Ramaya not to say anything about the incident to the public. He was sure that the people of the village wouldn't take well to the idea of having a jinxed person for a ruler. Ramaya agreed. When the villagers saw Ramaya returning with the gifts, they assumed that the rumour was false and that the king had given the gifts to Ramaya as compensation. They were ashamed of their behaviour and swore that they would never
ignore Ramaya.
