       FUNCTIONS OF ENTREPRENEUR  1). Innovation:                    Entrepreneurs play a vital role in driving innovation and value in the marketplace. The entrepreneur is responsible for testing markets, inventing new markets and uncovering demands within individual markets. The entrepreneur dynamic is fueled by creativity, competition and the motivation to succeed within a society.    2). Risk taking:                          Risk-taking is the most important function of an entrepreneur. He has to pay to all the other factors of production in advance. There are chances that he may be rewarded with a handsome profit or he may suffer a heavy loss. Therefore, the risk-bearing is the final responsibility of an entrepreneur.  3). Organizing function of an entrepreneur:                                                            This refers to bringing together the men, material, machine, money, etc. to execute the plans. The entrepreneur assembles and organizes the abovementi

It aims at bringing innovation and building ideas quickly. Concept of Entrepreneurship  An enterprise or business is created by an entrepreneur. The process of creation such an enterprise or business is called “entrepreneurship”. • Entrepreneurship is a process of actions of an entrepreneur who is a person always in search of something new and exploits such ideas into gainful opportuni

  Working of Disc Brake:  Disc brakes are a type of hydraulic brake commonly used in cars, motorcycles, and bicycles. These brakes consist of a metal rotor attached to the wheel hub and a brake caliper that contains one or more brake pads. When the brake pedal is pressed, hydraulic fluid is forced into the caliper, causing the brake pads to press against the rotor, which slows down or stops the rotation.  The working of disc brakes can be summarized in the following steps:  1. The brake pedal is pressed, which activates the brake master cylinder.  2. The master cylinder sends hydraulic fluid to the brake caliper.  3. The brake caliper contains one or more brake pads that press against the metal rotor.  4. Friction between the brake pads and the rotor slows down or stops the rotation.  5. Some disc brakes also have a rotor with slots or holes to improve heat dissipation and reduce brake fade.

  Functions of Brakes:  Brakes are essential components of any vehicle or machinery that require stopping or slowing down. The primary functions of brakes are:  1. Stopping the vehicle/machinery quickly and safely  2. Controlling the speed of the vehicle/machinery  3. Preventing the vehicle/machinery from rolling back on slopes  4. Reducing wear and tear of the tires or other moving parts  5. Protecting the transmission system from damage due to sudden stops or jerks Types of Brakes :  1. Mechanical Brakes : These brakes use cables or rods to activate the brake shoes, which press against the rotating drums or discs to slow down or stop the vehicle/machinery. Examples of mechanical brakes include bicycle brakes, hand brakes on cars, and some industrial machinery.   2. Hydraulic Brakes: These brakes use hydraulic fluid to transmit pressure to the brake shoes or pads, which press against the rotating drums or discs. Hydraulic brakes are commonly used in cars, trucks, and othe

  THERMODYNAMICS:- It is the branch of engineering in which we study about the conversion of heat   energy into mechanical energy. THERMODYNAMICS SYSTEM :- It is the region or area around the space where all the thermodynamics process takes place or thermodynamics analyis is done.   **SURROUNDING:- Every thing apart from the system is called surrounding.   *BOUNDARY:- It is an imaginary or real surface which separate system and surrounding.   * TYPES OF THERMODYNAMIC SYSTEM There are three types of thermodynamics system. 1.    Open system:- A system in which mass as well as energy can transfer from system to surrounding or surrounding to system is known as open system. 2.    CLOSED SYSTEM:- A system in which mass remain constant but energy can transfer from system to surrounding or vice-versa. 3.    ISOLATED   SYSTEM :- A system in which neither mass nor energy ca

      Conventional Design Process There are six steps involved in the conventional design process as discussed below:   1. Recognition of need  • The first step in the designing process is to recognize necessity of that particular design.  • The condition under which the part is going to operate and the operation of part in that particular environment.  • The real problem is identified by knowing the history and difficulties faced in system. 2. Definition of problem  • The design involves type of shape of part, its space requirement, the material restrictions and the condition under which the part has to operate.   • The basic purpose of design process has to be known before starting the design.  • A problem may be design of a simple part or complex part.  • It may be problem on optimizing certain parameters. 3. Synthesis of design  • In this, it may be necessary to prepare a rough drawing of design part.   • The type of loading conditions imposed on the parts.  • The type of sh

 Reasons for Implementing a CAD System  1. To increase in the productivity of the designer:-                                                                             The CAD improves the productivity of the designer to visualize the product and its components, parts and reduces time required in synthesizing, analyzing and documenting the design.   2. To improve the quality of design:- o CAD system permits a more detailed engineering analysis and a large no. of design alternatives can be investigated.   o The design errors are also reduced because of the greater accuracy provided by system .    3. To improve communication in design:-                                                          The use of a CAD system provides better engineering drawings, more standardization in drawing, better documentation of design, few drawing errors.   4. To create a data base for manufacturing:-                                                                 In the process of creating the docume

Compressors are mechanical devices that are used to increase the pressure of a gas or vapor by reducing its volume. There are various types of compressors available in the market, each with its own unique features and advantages. Two of the most commonly used compressors are Hermetically sealed and Semihermetically sealed compressors. Hermetically Sealed Compressors:-                                                 A hermetically sealed compressor is a type of compressor that is completely sealed and is designed for small applications like refrigeration and air conditioning units. The hermetic compressor is called so because its motor and compressor are placed in a single sealed casing. The casing is welded or brazed shut, which prevents any gas or liquid from leaking in or out of the compressor. The hermetically sealed compressor is also known as a ‘sealed compressor’ or a ‘closed compressor.’ These compressors are often used in refrigeration systems and air conditioning un

  Clamping is a process used in various industries to hold or secure objects in place during machining, welding, assembly, or other operations. The basic principle of clamping involves applying force to hold the workpiece firmly in position, preventing movement or displacement. There are different types of clamps available for various applications, and here are the basic principles and types you mentioned: Strap Clamps : Strap clamps use a flexible strap or band to encircle and secure the workpiece. They typically have a ratchet or cam mechanism that tightens the strap, creating tension and holding the workpiece firmly. Strap clamps are versatile and commonly used in woodworking, cabinetry, and general assembly. Cam Clamps : Cam clamps utilize a cam mechanism to apply pressure and secure the workpiece. The clamp consists of a lever with a cam-shaped head that engages with the workpiece when the lever is pressed down. Cam clamps are qui
