Designing a wrench involves determining the size, shape, material, and functionality based on the intended use.
Identify the purpose of the wrench (e.g. for automotive, plumbing, or construction)
Determine the appropriate size and shape of the wrench based on the target fasteners
Select the material for the wrench based on strength and durability requirements
Consider additional features such as adjustable jaws or erg...
Stress-strain diagram shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
Stress is the force applied to a material, while strain is the resulting deformation.
The diagram typically shows a linear elastic region, followed by a yield point, plastic deformation, and ultimately failure.
Materials can exhibit different behaviors on the diagram, such as brittle, ductile,...
Copper has higher thermal conductivity than steel.
Copper has a thermal conductivity of around 400 W/mK, while steel typically has a thermal conductivity of around 50 W/mK.
This means that copper is a much better conductor of heat compared to steel.
Copper is commonly used in heat exchangers and electrical wiring due to its high thermal conductivity.
Steel, on the other hand, is used in applications where strength and...
Bending stress is a type of stress that occurs when a material is subjected to bending.
Bending stress is calculated using the formula: σ = M*c/I, where σ is the bending stress, M is the bending moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia.
Bending stress is commonly seen in beams, bridges, and other structures subjected to bending loads.
The formula for bendi...
Subcooling and superheating are processes in which a substance is cooled or heated beyond its saturation point, respectively.
Subcooling is the process of cooling a liquid below its saturation temperature without changing its phase.
Superheating is the process of heating a vapor above its saturation temperature without changing its phase.
Subcooling helps in increasing the efficiency of refrigeration systems by ensur...
A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle.
Chillers are commonly used in air conditioning systems to cool buildings or industrial processes.
They work by transferring heat from the liquid being chilled to a refrigerant, which then flows through a compressor and condenser to release the heat.
The chilled liquid is then circulated through the system...
Saturation temperature of refrigerant is the temperature at which the refrigerant changes state from liquid to vapor at a given pressure.
Saturation temperature is specific to each refrigerant and pressure level.
It is an important parameter in the design and operation of refrigeration systems.
For example, the saturation temperature of R-134a at 1 atm pressure is -26.1 degrees Celsius.
VARS stands for Variable Air Volume Reheat System, while VCRS stands for Variable Chilled Water Reheat System.
VARS controls the air flow rate and temperature to maintain comfort in a space, while VCRS controls the chilled water flow rate and temperature.
VARS is commonly used in HVAC systems for commercial buildings, while VCRS is used in systems where precise temperature control is required.
VARS can be more energy...
To prevent plastic defects, design engineers use methods such as mold flow analysis, material selection, gate design optimization, and part geometry considerations.
Perform mold flow analysis to identify potential issues before production.
Select the appropriate plastic material based on the requirements of the part.
Optimize gate design to ensure proper filling and packing of the mold.
Consider part geometry to minim...

- Q4. What is design library in solid Works?
- Ans.
Design library in SolidWorks is a feature that allows users to store and reuse commonly used parts, features, and assemblies.
Design library provides easy access to standard components like screws, nuts, bolts, etc.
Users can drag and drop items from the design library directly into their designs.
It helps in saving time by reusing pre-designed components instead of creating them from scratch.
Design library can be customi...
- Q5. Joining of 2 sheet metal process?
- Ans.
The joining of 2 sheet metal processes can be achieved through methods like welding, riveting, adhesive bonding, or clinching.
Welding: involves melting the edges of the two sheet metals and fusing them together.
Riveting: involves using metal fasteners to join the two sheet metals together.
Adhesive bonding: involves using a strong adhesive to bond the two sheet metals together.
Clinching: involves deforming the edges of ...

- Q1. Plastic defects?
- Ans.
Plastic defects refer to imperfections in plastic materials that can affect their performance and aesthetics.
Surface defects: Scratches or blemishes on the surface can affect appearance and performance.
Dimensional inaccuracies: Parts may not meet specified dimensions, leading to assembly issues.
Bubbles or voids: Air pockets can weaken the material and affect structural integrity.
Color inconsistencies: Variations in col...
- Q2. Which method are used to plastic manufacturing?
- Q3. Plastic design consideration?
- Ans.
Plastic design consideration involves material selection, part geometry, manufacturability, and environmental impact.
Material selection based on properties like strength, flexibility, and temperature resistance.

- Q1. Static load vs dynamic load
- Ans.
Static load is a constant force acting on a structure, while dynamic load is a varying force that changes with time.
Static load remains constant over time, while dynamic load fluctuates.
Examples of static load include the weight of a building or a bridge, while examples of dynamic load include wind or earthquake forces.
Static load is easier to predict and design for, while dynamic load requires more complex analysis an...
- Q2. Dynamic load vs static load
- Ans.
Dynamic load is a moving or changing force applied to a structure, while static load is a stationary force.
Dynamic load is a force that changes or moves over time, such as a moving vehicle on a bridge.
Static load is a constant force applied to a structure, like the weight of a building on its foundation.
Dynamic loads can cause vibrations and fatigue in structures, while static loads typically do not.
